Chemistry

First Lab, Air Purification System Integration Laboratory.

On the table was a 1m ² model house that embodied a single floor of the building.

Jungwoo turns on one side toward the filter team preparing for the test. Kim Tae-san smiled and raised his thumb to Jungwoo.

While feedback on the hemispheric filters presented to the House took several days to be revised, the five-stage filters were now applied.

I'm curious about the results of the friendship pommel.

The problem was that I couldn't talk to Mei at all because I only spent the afternoon with the filter team.

‘I don't know if there's a chance. ’

Measurement of the facility team started while thinking.

The model house was visually inspected and continued to leak test the installed mini-frame and airflow distribution test.

Let the wind test begin.

The roof of the model house was covered with round hemispherical glass.

A 3D model appeared on the monitor that clearly looked inside the model house. I remembered the information of the wind moving along the fan that began to spin.

Mei watches carefully and finds a spot.

There is not enough wind in the end.

Structurally, it's the farthest thing from here. To increase the amount more than this, you have to subtract one more line.

It is useless in buildings that can only be used with conventional ventilation lines.

An expert from the facility team said that it was unfair after not being able to reply at that moment.

It is structurally impossible for any company to come.

"Impossible? Then is there no other way to tell these people that they need to eat structurally bad air? Sounds to me like you're giving up next week's bid.

I turned my gaze toward the model house, not the monitor for the two conversations. The ventilator on the exterior wall of the building was spinning without any rest, but it was unable to quickly vent all the air inside.

Mei pointed to the room in question and told the filter team.

Please add a bypass filter for internal circulation where there is not enough wind.

Kim Tae-san immediately reacted.

Why put the structural issues of the appliance team on the filter team?

"Aren't people building systems like ours?

Yu said. I think you're still confused about something. We're trying to keep the air clean. We're not trying to build a clean room. If you say there's not enough wind, here's the end of the air. Our 10-step filter is enough to cover it.

It seems that there is a great distance between Mr. Kim and me when it comes to drinking air. I'm sorry.

“She always says she's sorry. All the time.”

Kim Tae-san grumbled.

Just like at the morning meeting, I had no choice but to turn my gaze around as I went just before the atmosphere became a fight. The facility team was left alone and silent, and the sensors and filters were looking at each other with sharp eyes.

‘When am I going to get a good look at you? ’

Jungwoo looked at the congressman who was looking at those teams with a worried face similar to his own.

“Dear Representative, ”

When Nazik called, the congressman said in a little voice, “Yes?” I replied.

“Bypass filter. Shall we make it?”

“Now?”

“It's small, so I'll be quick. ”

The House of Representatives thought about it and pointed to the room across from Jungwoo.

“All our filters are in lab number two. ”

Jungwoo and congressman, who had left the Integration Laboratory briefly, immediately entered experiment number two.

Jungwoo put on gloves straightaway and turned his eyes to a sample of the KG electron air cleaner filter lying on the table.

A paper-shaped filter that looks like Budchat flesh. Once it was cut to the size of the fan line of the model house.

“About the size of this? ”

“That's enough. I'll make a bypass connection. ”

The House of Representatives also began assisting Jungwoo in his work.

‘Let's hold still.'

The performance of nanofiltration membranes and absorption membranes, identified by molecular field of view, was optimized for the molecular structure of flowing water as expected. KG electrons that transformed it into a form that could be used for air were great, but in the fight against ultra-fine particles, it was difficult to achieve optimal efficiency.

‘We don't have time to make amends. ’

Jungwoo recalled a combination that could open a refrigeration facility in which catalytic compounds were stored and adsorb emerging public hazards in the head.

‘Acids, bases, volatile organic compounds, carcinogens, odors · · · · · ·. ’

A mist that mixes reagents like a machine once every 5 seconds and produces a catalyst to be applied to the filter in a flash time and returns to the table. The House of Representatives who were watching the process had no choice but to get bigger eyes.

“Jungwoo. Now that. ”

“Oh, this combination is temporary. I'll find something more sophisticated for you later. ”

After sprinkling the catalyst on the filter, Jung sent a bunch of dust stars to help them absorb better.

“Done. Here. ”

Though Jungwoo took one filter, House of Representatives plugged into the model house attachment.

Back in the Integrated Laboratory, 10 minutes later, there was a window of sensory measurements to detect contaminants.

Formaldehyde 3.31 ppm, Toluene 2.87 ppm, Hydrogen Sulphide · · · · · · ·.

Thick atmospheric contaminants were detected, rising on the monitor, and the most important microdust level was detected as' 89 μg/m3 ’.

Jungwoo nodded, looking inside the glass with actual molecular vision. It appeared almost error-free when given the proportions.

Kim Tae-san also watched the results without saying anything.

Is the sensory team's ability to measure reliable, even in combat? ’

So I was trying to get out of the molecular world, but there was one thing that stood out in Jungwoo's view.

Heavy lead constrictions have congested on the part of the external fan spinning to create a virtual atmosphere. The results of the monitor detected through the sensor indicated that the lead reading was normal to '0.4 μg/m3’ due to the low phenomenon.

If there was a problem, I had to tell him. I raised my hand without hesitation.

I have a question.

Mei's gaze flickers as Jungwoo opens her mouth in silence.

If there is a cluster of pollutants on one side of the atmosphere, how should we detect them?

Mei said in Jungwoo's question.

The atmosphere is circulating. Just make sure you detect the air coming in.

But if a certain contaminant suddenly reaches, uh, 0.4 micrograms and then 10 or 20 in a single shot, Can our filters handle that?

What are you talking about? Who puts poison gas in the building?

Jung, who was looking at the monitor, slightly directed the dust star towards the air where the model house was located. A free electron through the glass roof touched the powder that was stagnant near the fan.

Lead powder was often sucked into the model house.

Beevik.

A beep was heard and the sensor reads' 15 μg/m3 'lead.

Like this. This is a serious air pollution situation.

Mae, as well as researchers from the sensor team, looked surprised and monitored. Lead-based fine powder swirled around the inside of the building and escaped into the atmosphere. Lead levels were fixed to a slight contamination, '0.9 µg/µg’, as originally intended.

Junchai. Is this a sensor error?

No. Lead components seem to be stagnating outside the sensor detection range.

The researcher's analysis revealed that Mei's gaze was toward Jungwoo.

How · · · · · · · · ·.

You shake your head at Mei's gaze as you understand the situation more accurately than a sophisticated sensor.

"Oh, it was just a question. This seems to be a coincidence.

Jungwoo looks back, smiling beautifully. Mei said she was watching such friendships.

The issue of reducing the detection angle of external sensors is correct. It was a good point.

While Jungwoo was surprised by the unexpected compliment, Mei continued.

Workarounds increase time to prepare for sensor detection. When all of a sudden there's a lot of pollutants coming in, the AI will analyze them and activate the auxiliary filter.

So you're prepared.

No.

Yes?

A study of secondary filters has not yet begun by the Filter Team.

Kim Tae-san pulled out his tongue just saying that he was only planning.

“The Yu Team Leader's criterion is so high that only the main filter takes time. ”

Kim Tae-san said, ignoring Mei's coldly sunken gaze.

Team Leader Yoo. Let's filter it out. It's almost time to go.

After the sensory measurements have been completed, the filter system has begun to be fitted to the model house. Jungwoo saw that Congressman had a slight connection to the bypass device, and he hoped that it would increase his trust with the filter team and Mei.

Mae instructs you when you're ready.

Contaminant Input.

A fully sealed model house with contaminated air was injected into the glass roof. Every sensor on the monitor flashes a red warning light.

Prepare to start the fan. One, two, three!

Oops, the air purification system started with a beep.

The monitor's readings fluctuate once and begin to shift from red to yellow to green, grumbling.

“Look, our filter. We did it in 10 seconds. ”

All the filter teams nodded satisfactorily at Kim Tae-san's muttering.

Mei looks carefully at the pollution levels that appear and says,

Bacterial detection is higher than the last test.

Isn't it still safe?

The lower the detection of bacteria, viruses, and volatile organic compounds causing respiratory diseases, the better.

No, Team Leader Yoo. Go outside. Can you smell better air than that?

Jungwoo scores on Mae's constant disagreement with Kim Tae-san. I asked the congressman in a hurry.

“Are there any days when you two aren't fighting? ”

“I've been involved in this project for a month, and I've only seen it once. ”

“When?”

“The day the lead researcher Kim Tae-san didn't come out for the year. ”

Jungwoo nodded his head and reassured me that there were few good Korean researchers in here with Mei. Improving relationships is not easy for anyone.

The senior researcher, Juni Tsai, who was watching the monitor, was suddenly surprised to summon Mei.

Boss, the numbers in Room 10 are weird.

Mae looks back at the monitor in this voice. The levels of pollution were significantly lower than room 10.

Kim Tae-san was surprised to see it and muttered.

“What is it? It's the least abundant here. Higher is higher. What's wrong? Is this a sensor error?”

The House responded in a low voice.

“I have a bypass filter designed by Jungwoo. ”

“What?"

Mei, along with Jun Tsai, carefully checked the number 10 and told Kim Tae-san.

This room. We have a six-step level of cleanliness in the nursery. Great improvement. Keep working on it.

Kim Tae-san, who was praised for starting the project for the first time, suddenly turned red. While I didn't really like Yumei's personality, who changed her attitude and high ratings immediately after fighting with her, Kim Tae-san didn't argue in Korean.

Jungwoo felt relieved and relieved that the atmosphere was well-equipped.

You fixed it as intended, didn't you? ’

If a project is 100 to 20 points short, like the slave ship said, one point a day. No, I thought I'd give you a half point and help you out.

After the measurement at the Integration Laboratory, the commute time came.

The House of Representatives went out and told Jungwoo.

“I'm so relieved to have Jungwoo. I think I can learn a lot. ”

“Please take good care of me for the next three weeks. ”

“I really am.”

The House of Representatives who bowed their heads politely disappears, and Jungwoo turns his back to go home. Then I ran into Mei, who was watching me.

‘Oh, my God. ’

Mei opens her mouth to Jungwoo.

Mr. Han.

Yes.

I said that no one can do anything well. Do you think you're wrong?

Confidence or humility.

Two choices that I regretted this morning floated in Jungwoo's head.

I don't know about that. However, as long as the ability can be reached. I will help you as much as I can. I'm not doing my research alone.

Mei, who was looking at Jigsy Jungwoo, said.

Please contribute a lot tomorrow. Like the bypass filter.

Apparently, she knows she did it.

As your Team Leader, I have one thing to say to your Deputy Chief. This project must be successful. In that sense, I have high hopes for you, which the professor and the congressman trust.

Mei, who has officially decided to become Deputy Chief, reached out her hand. Jungwoo nods and accepts her handshake.

* * *

Starfice Building, Gangnam-gu Busan Boulevard.

Jungwoo got out of the taxi and looked at the five-story building, surrounded by dim lighting. Like the entertainment company's building, the design was clearly different from the surrounding buildings.

I also noticed a photograph of the skylight.

Hotel design as long as the view of Venice is out the window. Yoon Iseul, who opened her eyes, was holding a guitar. My hair was tousled on one side, and my skin was especially white and radiant.

‘That's cute. Beautiful. ’

Experts would have taken it, so of course they would have captured the concept that would deepen the hearts of fans. I saw the text on the side.

Yoon Lee Seol's single album ‘On lockdown’/Released March 26!

"What song? Of course it's good, right? ’

Looking at her in the big picture, she shakes her head as she recalls what happened on the beach. The more vividly I remembered that day.

How can I forget? That beauty on the billboard, she wrote me such a thoughtful letter. When I remembered the kiss, I finally sighed.

‘That's why I came here. What the hell are you talking about, taking him to Dr. Moon? ’

Jungwoo, standing in front of the automatic door at the entrance, texted Yoon Lee Seul.

[I've arrived.]

The answer came right away.

[Shared room on the second floor.]

Short, emotionless characters. It's been like this since lunch. She lets out a long sigh of relief in her response, not even the slightest irritation.

The switchboard opens and closes to see what was being manipulated from the inside. Jung stepped forward and said awkwardly, because he didn't see anyone.

“Excuse me.”

Despite the exterior of the building, the interior was covered with a resting area that looked like a baby music room. In the meantime, you see words with note marks such as an editing room and recording room, and a staircase at the end.

“It looks like a design exclusively for Yoon Yiseong. ”

“Yes, the concept. ”

You mutter to yourself because it's too unpopular, but you hear someone's voice.

“Nice to meet you, Mr. Jungwoo. ”

He turned his gaze and was the Chief of Intelligence. Sitting on a table in a space like a music cafe, he told Jungwoo.

“If you're not busy, can we talk for a minute and go up? ”

“Lee Seol over · ·”

“That Lee Seo-yeol. He's asking me to buy him some time. ”

“Ah.”

When Jungwoo sat next to him, his director gave him a glass of water.

“You don't drink coffee, do you? I heard that.”

“Yes, this will do. ”

He opened his mouth while watching the spring drink water.

“Until recently, I was very grateful to Mr. Lim Woo. He's been a lot brighter since he went to the clinic. ”

“Something doesn't seem right now. Haha.”

Unlike Jungwoo, who smiled awkwardly, his face was solemn.

“The same goes for gratitude. Inspired by his work with Jungwoo, Lee's teaser reaction to the new song is unusual. Jungwoo's travel video is also popular. But there's one thing I don't understand. When it should be full of joy. ”

Chief Ji pointed up.

“Our singer has been stuck there for a week and has been paying for both doors. Preparing for the showcase as an excuse, pissing me off. ”

“Uh, mm-hmm. ”

Speaking in reverse, the chief seemed to notice.

“In my view, Lee Seol did something to Mr. Lim Woo. ”

I popped a heart-style teaspoon in a mug with the fingertips of the head.

“Mr. Jungwoo said no to that. ”

I couldn't help but smile at the dean's gaze as to why so many men across the country were so cheerful and glamorous to reject the stellar majesty.

“Let me ask you straight away. Isn't our theory pretty? ”

“It's beautiful. It's full of garages. But I have a situation that I can't explain. ”

He even noticed bitterness on the smile on Jungwoo's mouth.

“I don't know what's so complicated about that. One, if you're qualified for that, think again. Is it true that a man who can hear that Lee Seol is not sorry is in Korea? I don't have enough for any man, on my own terms. ”

“You've got a good point. ”

“Even though it's been over five years since we got married and they're all dead. But when he hears this song, there's a time when he gets a headache. Especially this new song. Does that mean anything to you? You do what you want. ”

During his vomiting of the heat, he heard an urgent step on the second floor stairs.

Tudadadada-dak!

“Chief!"

Suddenly, Yoon Lee Seol sighed intensely and looked at Chairman Ji.

“Jungwoo, what are you doing? ”

“No, I think I'm thirsty as I go by. Drink some water. ”

Jungwoo was surprised by this answer.

Chief Ji glanced at Jungwoo and turned away from Yoon Iseol's gaze. Jungwoo realized that she had never asked for time.

“Ugh, really. ”

Yoon Lee Seol once looked at Jungwoo and said with his head down.

“Get up here! Now! ”

Then he jumped off the road stairs and disappeared. Jungwoo pointed to the other side of the hall where she ran and asked the manager.

“Has Lee Seol been like that lately? ”

“More. Today is Mr. Lim Wu's coming, like an angel. ”

“Aha · · · · · · · · · ·. ”

Jungwoo fearfully headed to the choir room on the second floor.

Sweet.

When I opened the door, I saw Yoon Iseol sitting on the chair. She was holding the guitar and faced Jung Woo.

Jungwoo greeted carefully.

“Long time no see · ·”

“Done. Contract in front of the desk. You have to sign there to give it to the road managers. Don't get me wrong, that's why I called you here. ”

“Got it · ·”

“And. Well, you're not even going to pay attention to me anymore. If you have any love left as a fan, you can watch this new song. ”

Without even giving him an opportunity to answer, Yoon Iseol looked at Jungwoo's eyes, touching his guitar with his fingertips like he was nervous.

She was the usual girl whose insides were revealed on her face.

‘Arthur, that's when you're done with your mind. ’

Jungwoo sat down and said.

“· · · I sign a long time ago. I'm just going to sit down for a minute.”

Yoon Yi Seol looked relieved. "” I turned my head. She clears her throat and puts her hands on the guitar.

Grrrrr.

On the quiet melody of the guitar that bounces off the soft harmony, Yoon Lee Seol's voice was overlaid.

- I have a crush on you.

The raw hair touched the body of the guitar. Jungwoo winced as soon as he heard the first lyrics. That day, a letter was written in a notebook I saw on the beach. The lyrics were coming out of her mouth as a song.

- This morning. How long have I been dreaming? I can't wake up from those magical times.

The song with the sincere emotion of Yoon Yi Seol continued for 3 minutes, above the emotional tone, which was inevitable and trembling in my heart.

- I want to keep looking. I close my eyes again. I think I'll see you in my sleep. Good night, you. I'll see you again.

The end of verse 2.

Jungwoo looked at Yoon, without saying anything.

Beautiful voices, the sincerity in them.

There is no man in the world who will not be shaken by a confession like this. Jungwoo had no choice but to empathize strongly with the chairman's words that there would not be enough for any man.

“Are you done signing? ”

Jung woke up to the question of Yoon Iseol who finished the song, unconsciously signed it, and looked back at her.

“I love this song. ”

“What about me?”

“Yes?”

“How good am I? ”

Since when did such a heartbreaking question become a constant thing between us? I wondered if Jung Woo's heart could live even if it thumped like this.

Yoon Iseol, who hesitated to answer, said.

“The next one is still 10 months later, right? Okay, let's go. ”

“Seolmin Lee · · · · · · · · ·. ”

Jung stood up and asked.

“Are you hurt anywhere? ”

“Why do you ask? Didn't you just sign and go? ”

I had to walk to the door to make sure Yoon Yi Seol's expression was resolved. In the meantime, asking me to go to the hospital with you is crazy. I'm just glad it looks the same as before.

‘We'll have to find another way. ’

He told Jungwoo who had his hand on the door hook that Yoon Lee Seol was waiting for him.

“Just in case. ”

Jungwoo's steps stopped.

“I have seven checklists left, and I did one with Jungwoo today. I'm going to do the rest with Jungwoo. Tell me now if you don't want to. ”

“No · · · · Riga. But what did you do today? ”

“I usually punch people who bully me. ”

“Looks like you're getting hit right. ”

Yoon Lee Seol said to Jungwoo, smiling peacefully.

“Who's finished? You haven't even hit him yet. ”

“You're really going to hit me? ”

Yoon Lee Seol smiled at Jungwoo who was surprised.

“There was an ad in there earlier. At the company with Mr. Jungwoo. ”

“That's · · · · · · · · · · · ·. ”

“I accepted and made a condition. If it's cool, why don't you come out with a male lead and a lover? The chief of staff liked it. ”

Jung Woo's face became half dazzled.

“Lovers? I've never done that before. You know that, right? ”

“That's it. I'm going to make it so pretty that I'm going out there, so get ready to shake it up. ”

Sweet.

Jungwoo came out of the hallway.

How many unexpected things happened today? I can't even count the numbers.

“Phew.”

Yoon Yi Seol held her ears to the door, checking the footsteps that were distant and sweeping her chest down.

Live with all your might.

If I sang like this every day, I might have twice as many fans. It was just one song, but my legs trembled.

I sat on the floor with my back against the door.

“I did good, right? ”

Stupefied, shaky face. I saw it clearly.

“Prepare to continue to like me. ”

Yoon Lee Seol smiled happily, holding both arms together. The fact that being as active as being in love hurts less. If it is difficult to go both ways, you can continue to go through the eighth lane from one side.
