In the living room of the Kosaka family.

"Senior Su Yu, please sit down." Kosaka Tong Nai took Su Yu to sit down, poured a cup of barley tea for Su Yu, and placed it in front of him.

Su Yu drank the barley tea, glanced at Kyosuke Kosaka who entered the living room, and smiled at him.

"Senior, I'm going to change my clothes, please wait for me here." Kosaka Tongno said to Su Yu and walked outside the door.

Kosaka Kyosuke watched Kosaka Kirino pass by him and sat on the sofa next to Su Yu.

"Are you dating Tong Nai?"

"I have known classmate Gaosaka not long ago, so they can only be regarded as friends." Su Yu shook his head.

He knew that Takasaka Kirino was using him, and he did not intend to be used by Takasaka Kirino.

"Is it just a friend?" Kosaka Kyosuke said in disbelief.

Kosaka Tongno went upstairs to change clothes, isn't she going on a date with Su Yu?

"You are Gaosaka's brother? My name is Su Yu, please take care of me." Su Yu stretched out his hand.

"My name is Kosaka Kyosuke." Kosaka Kyosuke and Su Yu shook hands.

"Kun Takasaka, can I call it that way?"

Kosaka Kyosuke nodded.

"Actually, before I knocked on the door, I hesitated for a long time outside the door, worrying that Gaosaka's parents asked me what the relationship is with Gaosaka. Fortunately, it was Gaosaka-kun who opened the door." Su Yu smiled.

"They are all out today and are not at home. Are you and Kirino really okay?" Kosaka Kyosuke tentatively asked.

"I already have a girlfriend, and Gaosaka also knows this." Su Yu replied.

"Then you and Kirino..."

"Actually, this matter is a bit embarrassing to say." Su Yu thought for a while.

"Huh?" Kosaka Kyosuke looked suspicious.

"My girlfriend has always been lonely, has no friends, and became a couple with me because we have a marriage contract. She likes to read comics recently, especially the kind of romance comics. I want to surprise her. So , I made an appointment with Gaosaka and asked her to choose that kind of comic with me.” Su Yu explained.

"That's it." Kosaka Kyosuke looked at Su Yu's expression and believed his words.

"Kaosaka-kun, you seem to be hostile to me, are you worried that I will take Tongno?" Su Yu joked.

"Sorry, I just misunderstood." Kosaka Kyosuke scratched his head, a little embarrassed.

"It's okay, I can understand your feelings. If I had such a cute sister, I would definitely worry about a boy cheating on her." Su Yu waved his hand.

"Thank you, Su Yu-kun." Kosaka Kyosuke said sincerely.

His gratitude is naturally to thank Su Yu for his understanding.

"You're welcome." Su Yu smiled.

"Senior, let's go." Kosaka Kirino appeared in front of the living room, changing into a cool and stylish outfit.

"Kaosaka-san, see you next time." Su Yu got up, said to Kosaka Kyosuke, and walked outside the door.

Kosaka Kirino's expression was a bit stunned. What happened when he went to change clothes?Why does the relationship between Kosaka Kyosuke and Su Yu seem to be getting better?

"Student Gaosaka? Don't be in a daze." Su Yu reminded.

Kosaka Kirino returned to his senses, glanced at Kosaka Kyosuke, and left home with Su Yu.

...

Leaving Kosaka's house.

Su Yu and Kosaka Kirino were walking on the way to the station.

Kosaka Tongno looked at Su Yu who was expressionless beside him, feeling a little uneasy.

Could it be that Su Yu saw her purpose?

Or did Su Yu see something deeper?

If Su Yu realized her secret, he would definitely hate her, right?

In case, Su Yu told others her secret...

"Senior Su Yu." Takasaka Tong Nai couldn't help saying.

Su Yu stopped and looked at Kosaka Kirino.

"Yes... I'm sorry, I deliberately let seniors go to my house." Kosaka Kirino lowered his head and said.

"You let me go to your house to make Kosaka-kun angry, right?" Su Yu said lightly.

Kosaka Tongno trembled, not daring to look up at Su Yu.

"Then, there is only one reason, you want Mr. Gaosaka to care about you." Su Yu whispered.

Kosaka Kirino's small hands clenched tightly, and his face instantly turned pale.

"Normally, this kind of thing should be done by girls who like Kosaka-kun, the purpose is to test Kosaka-kun or let Kosaka-kun care." Su Yu said one word.

Kosaka Tongno bit her lip, her mind was in chaos, there was only one thought, when it was over, Su Yu discovered her secret.

"Student Gaosaka, your real commission, I seem to understand what it is." Su Yu slowly approached Gaosaka Tongno and said in her ear.

Kosaka Kirino's face was full of fear and a little pleading.

"Are you begging me not to tell anyone?" Su Yu looked at Kosaka Kirino's expression.

Kosaka Kirino nodded.

"Since it is a request, then you should show some sincerity?" Su Yu looked at Kosaka Kirino.

"I...I'm willing to do everything, please don't tell others about this..."

"Anything?" Su Yu confirmed.

Kosaka Tongnon let out a hum and lowered his head.

"So..."

Kosaka Kirino's heart tightened.

"Become my girlfriend." Su Yu stretched out his hand, held Kosaka Kirino's little hand, and kissed the back of her hand lightly.

Kosaka Tongno was stunned. When she saw the gentleness in Su Yu's eyes, she understood Su Yu's thoughts for a moment.

"Senior, I..."

"If you don't agree, then I will tell your parents your secret." Su Yu said seriously.

"Senior, I know you want to help me..."

"Did you misunderstand something? I didn't mean to help you. I just think you look pretty, just right. I caught your weakness again, so I took the opportunity to offer this condition..."

"Senior, don't pretend to be a bad person anymore. I know, you want me to forget him, forget this wrong relationship." Kosaka Kirino said, tears fell.

"I really can't do anything with you." Su Yu looked at Takasaka Kirino's tears, sighed, raised his hand, and helped her wipe the tears.

"senior…"

Kosaka Kirino hugged Su Yu and cried.

Su Yu looked at Takasaka Kirino who was out of control, stroked her long hair and comforted her in a low voice.

Kosaka Tong Nai leaned in Su Yu's arms and said nothing, but tears couldn't stop streaming.

Her distress, her pain, her sorrow and entanglement, secrets that no one knows, secrets that no one dares to say, have always been pressed in her heart.

She didn't dare to talk to anyone, she could only silence her feelings.

Now, Su Yu knew this secret, and Su Yu was still willing to help her.

Kosaka Tongno believed in Su Yu, and when she saw the gentle touch in his eyes, she knew that he would rather be a bad person and want to help her.

a long time.

Kosaka Kirino choked, his tears stopped.

"If you keep crying, you won't be pretty." Su Yu gently wiped away the tears from the corners of her eyes.

"I'm sorry, senior." Kosaka Tongno looked at Su Yu's clothes with guilt.

"It's okay, it's too early for the offline party, just to go shopping in the mall." Su Yu reached out to her.

Kosaka Tongno didn't hesitate and put his little hand in Su Yu's hand.
