I seem to belong to a club called the Department of Family Sciences, and after school I came to the Department of Family Sciences as Sana told me.

Before I lost my memory, my sister and I had a secret relationship.

"What should I do..."

"... what's wrong?"

The small, uninhibited voice was due to its many performances.

After all, it seems that people who remember and people who don't.

I had unexpectedly remembered my seat in the classroom, the location of the waste box, the location of the biology room, etc.

The more I became a family member, a lover, or an important person, the more relationships and memories slipped out.

Kazuta sat in my seat and activated the mobile game console.

"... since lunch break, Sa-chan is in a good mood.Unusual..... "

"Yeah. Really?

"... yeah. I don't know why."

Sana said we shouldn't tell anyone about our relationship in private, so she probably didn't tell us much about it.

Of course, your relationship with the teacher is a secret.

I don't know who to turn to for help...

"Are you attracted to romantic love that you shouldn't do?

"... I'm not very interested in love... I'm sorry."

"Yeah. For example, if my sister really liked my brother, what would he do?"

"What? Sa-chan, did you say something?

"Eh, what is it?

"... nothing.... as I told you before, if you're liked by the opposite sex, give it a proper huff.I think it's my brother's kindness to crush you to pieces. "

Looking at me, I dropped my eyes on the screen at hand.

Did they say that before...?

"Ah, brother, he's already here!

Ah, Sana.

"... Sana-san?

Kazuta frowned.

"Let's go home. We're playing in Sana's room today!

"No, I had plans too...."

"... respectful words?

Sana pulls her hand to get me up.At the same time, the opposite hand was pulled by the player.

"Kana?

"... Seiji, something's wrong.Does it have anything to do with Sa-chan's mood?

"Ah, I don't think so.It's none of your business. "

"... there is."

"Gik"

Sana, who shrugged her neck, sat on the chair with a sense of purpose.

And I learned a lot about the weird things that happened to me yesterday.

"... I see. And with all due respect, Sana-san...... aren't you breathing weird things into your innocent Seiji?

"Fu, I'm not blowing in!So, what's so weird about that?

"... the good thing about memory loss is that they're actually dating each other as lovers..."

Gikyun!

Vine and Sana were easy to understand and rigid.

Are you with me?So, Gikoon.

Does that mean...?

"... don't lie, Sa-chan.... I know how much I want to love you with my beloved brother. "

"I don't want to have sex with my brother!Why is Sana with her brother..... "

"So, what you said yesterday was a lie?

Sana frowned bitterly.

"I'm sorry. Yesterday was a lie.I'm just kidding.Niisan, it's easy to believe.I'm surprised.Ah, that's impossible.... "

It seems that I didn't go out with my sister.

I'm glad... I'm not double-stranded.

Sana ran out of the family ward.

I saw my cheeks getting wet.

Maybe he really liked me.

When I try to chase him, he shakes his head.

"... no. Makoto, please don't console me."

"Why? It seems like I'm the cause, and I'm going to make a little noise...."

"... no. Makoto, if you have someone you like... you shouldn't go after her."

Ugh!? Let me, do you know the relationship between the teacher and me?

"I wonder what she meant...."

"... I'm too upset.... I don't know the details, but I know she's here. "

That means he doesn't know he's a teacher.

I'm glad...

"... Sa-chan is always a bad guy.I just like it purely. "

"If anyone likes me, I won't... Makoto Sanada will."

You might not even notice.

"... yeah. In fact, it is.But there's something wrong with Sa-chan.... perhaps you also know, but I won't admit it under the guise of being dull, so the wounds are getting wider and wider... anyway, let Sa-chan handle it. "

Grabbing the bag, Kazuta leaves the family department.

"... relationships, Taiheng"

I snapped at the end.

If you think about it carefully, your phone's email was full of "Shuki Haruka", and so was the incoming call.

I thought it was unnecessary to contact you because I live in the same house, but if you are not dating or a lover, I am satisfied.

Um? Is Sanada-kun alone?Today was supposed to be activity day..... "

The teacher came with a decent face.

I'm just glad it fits my eyes.

It seems that Makoto Sanada really likes this teacher.Me, too.

"It's like there's a lot going on, and it's like I'm home."

Oh, yeah.I'm almost done with work. Have you eaten dinner?

"Eh, okay?

"Yeah."

Is it okay for me to be a teacher without memory?

As I walked home as I became suspicious, my teacher picked me up in a car that was just too difficult to walk by.

As the rain pounded on the windshield, I asked myself in the car.

"You're really dating me, aren't you?Don't you hate this state?

"Hmm, different people are different, but even if I don't remember, I realized that Makoto is Makoto, so I took a lunch break.I don't think so.

"Eh, where was I?

"Succulent Tiny"

"There!?

"That's also true, ufufu, and keep it to yourself.I remember before we went out. "

The teacher looked happy with this.Aren't you worried that I might not be able to go back?

By the time I arrived at the beautiful apartment, it was raining.

"Stairs, be careful.It's slippery after it rains. "

"Yes."

"Fugga!?

Looking back at the scream as if he had fallen, the teacher glanced at one point.

"Ahhhhhhhhhhhhhhhhhhhhhh..."

The shirts and T-shirts hanging from the hangers were dried up in front of her eyes.

Halfway down the stairs, there were colorful underwear that resembled the teacher's.

... eh, eh...Ah, that's what I'm wearing...

As he glanced at it, he slipped his legs and fell down the stairs.

◆ Makoto Sanada ◆

"Yikes....."

"Makoto!? Are you okay!?

Shuki-chan looked at me worried.

... that.

Shuki-chan's apartment?

"I'm fine... Haruka-san, what are you doing...?

"What are you doing... ah, I said Haruka-san instead of the teacher!

"Yeah, just the two of us.Oh, I made a mistake. Sensei "

"Don't say it again, I'm not mistaken!It fits! You're already doing this on purpose, right?

With an angry face, Shuki-chan pinched my cheek lightly.

I remember where Sauna hit me with a cushion, but I don't know what happened after that.

I'm wearing a uniform, and I'm in Shuki-chan's apartment, and I don't know.

Looking at my phone, the date was about a day ahead of my memory.

I thought you were on time, but I don't think so.

I had Shuki-chan come up and tell me what happened.

"I can't believe I lost my memory..."

I don't know if I'm on time or not.

Shuki comes next to the sofa.

"Back to the fresh Seiji, the reaction was cute once and for all... ♡"

Where are you adoring me?

"Didn't you worry?Maybe I won't go back. "

* giggle *, Shuki-chan wrapped her arm around my arm.

"You're asking the same thing.Makoto is Makoto, so I was confident that I would fall in love again. "

When you say such a thing to the ball, it illuminates...

"Makoto, you're shining!

"It's not illuminated!

"Makoto, don't you remember?Previously on "

"Yeah. Not at all.... but even if I lose my memory, I'm confident that I'll like Haruka-san again."

"But oh... that's what makes me happy right away."

Turn your other arm around my neck and look at each other as you breathe.

The warm, soft feeling of Shuki-chan's lips made a chuckle.

"Which one was better for me?No memory. "

"Seiji nowadays ♡"

Even though it rained again, I noticed it.

When I got home, Sauna took a gentle attitude for some reason, but I generally went back to my old life as I knew it.
