The person who likes me is a yandere.

Chapter 5 is ridiculous!

Why? Why can you still laugh at a time like this?

I felt that I could vaguely glimpse the abnormality of the Renjo family from the depths of Ayase's unnaturally clear eyes, and I felt a chill run down my spine once again.

"Whoosh! Wow!"

Ayase suddenly yawned.

"I've talked a lot, and suddenly I'm sleepy. Let's go to sleep, brother."

"Hmm, that's right... Let's do it that way."

To be honest, I'm not sleepy at all. But I'm not confident I can process any more information today, and I hope she gets out of here as soon as possible.

"Then, brother, be careful not to catch a cold."

Yeah, you too. Goodnight.

"Whoosh~~~"

Ayase, looking completely ready to get into bed, stood up...

Goodnight~~

...then she crawled into my bed.

"What the hell?! What are you doing?!"

"Hey? Brother, what's wrong?"

Ayase poked her head out from under the covers.

"You're asking what happened?! Why, why did you crawl into my bed?!"

"Ayase already said that she can't sleep after changing her pillow. My brother also said it's okay to use it."

"Huh? You mean the pillow you brought? Could it be the one under my head? Okay, okay, here you go."

"No, that's not it~. Ayase's pillow is this~"

"hey hey"

Ayase pushed away the pillow I offered and hugged me tightly in a style reminiscent of wrestling.

"Ayase's Personal Brother Body Pillow -☆"

"Ugh! You idiot, you idiot, let me go! What are you doing?!"

This is really bad, this scene is truly awful. A brother sleeping in bed with his sister? That's absolutely utterly perverted. Especially since Ayase is wearing a gym uniform, I have no way to explain myself.

"Hey? Brother, what's wrong? Your face is so red!"

"Of course I'll blush! Alright, get out of bed now."

"why?"

...And she even asked why? Is this girl serious?

"Why can't I sleep with my brother?"

Damn it, that look in her eyes meant she was serious.

"Brother and sister sleeping in the same bed, that's obviously problematic."

"Hahaha, oh my god, what are you saying? This is hilarious!"

Why? Why does she always laugh when I least expect it?

"Didn't my brother tell me that healthy siblings must sleep in the same bed before they become adults?"

……What?

"Brother, you remember, right? Because... it's common sense."

What exactly did you instill in my sister, the me before she lost her memory?!

Goodnight, brother.

"Wait, don't turn off the lights!"

"Wow, my long-lost brother's body pillow!"

"Don't grab my arm!"

Don't put your legs on my waist. Don't rub your forehead against my ear! Don't breathe on my neck!

Damn it, what's with this saccharine creature?! It's so soft even though it has hardly any flesh on it.

"Ugh, I can't take it anymore!"

"Ah ah!"

I struggled to throw off the covers and turned on the bedside lamp.

"Brother, what's wrong? Is it acting up again? Are you going to resort to violence again?"

"No, no, this is a perfectly healthy reaction from healthy siblings! A healthy brother would react this way if his healthy sister used him as a body pillow in his healthy bed!"

"...Brother, I'm sorry, Ayase doesn't understand what you're saying at all."

I don't understand either, damn it!

"Please, please, please go back to your own bed tonight! Get me a different room and a different bed! I'm begging you!"

As the older brother, I knelt down on the bed and bowed to my younger sister who was wearing a gymnastics uniform... I wonder what kind of misunderstanding this dangerous scene would cause if others saw it.

"I see... I understand."

Sincerity can move mountains, and Ayase understood my sincerity, nodding somewhat reluctantly.

"Ayase, do you understand me now...?"

"Hmm. My brother hasn't regained his memories, so he sees Ayase not as his sister, but as an ordinary girl. It would be strange for a boy and a girl who aren't siblings to be in the same bed... wouldn't it?"

"...Yes, that's right, that's exactly it."

If we had to put it bluntly, the way these siblings sleep together is far more bizarre, but that's irrelevant now.

"I'm so sorry, can you leave now? I'm going to sleep too."

"Okay, sure. I'll be lonely... but Ayase will try her best to sleep alone!"

Like a soldier going into battle, Ayase gave me a firm salute, then slowly placed her hand on my shoulder...

"I'm leaving now, goodnight...brother."

She gently brought her face closer.

...Huh?

"I'm leaving, brother. Tomorrow you'll become Ayase's brother again, okay?"

Ayase beckoned through the crack in the door and then slammed it shut.

"—Guhaa"

At the same time, I also collapsed heavily onto the bed with a thud.

What was with that attack just now?

The bullet wound to his cheek… no, his entire head was on fire, turning bright red. This was completely unexpected, something neither preventable nor avoidable…

...A goodnight kiss.

A brutal bomb capable of blowing away even the last remaining fragments of memory.

Chapter Six: Not Yet a Handsome Guy

Today, just like yesterday, I feel like I'm slowly waking up, being dragged ashore little by little from the water.

A heavy pressure, slowly spreading from my feet, pounded against my chest, caressed my throat, pulled at my cheeks, and then pried open my eyelids. Finally, it was as if it were replacing the original darkness—

"Ah, she's awake. That's great!"

An extremely cute girl's face forcefully filled my field of vision.

"Ugh, what's going on?!"

My first instinct was to jump away, but I couldn't lift my body at all. This wasn't because my body, which had been dormant for a week, was out of control.

"Good morning, brother. What a refreshing morning!"

...It wasn't because my sister was in a really good mood and was riding on my back.

"Freshness my foot! What are you doing! Why are you here... cough cough cough cough"

I can't take it anymore, my throat is so dry after just waking up, it hurts as soon as I shout.

"What else can I do? Of course, I'll wake my brother up! Isn't it a little sister's duty to ride on her sleeping brother and wake him up?"

They started fooling around first thing in the morning...

"This is common knowledge that my brother told me, don't you remember?"

What exactly did you instill in my sister, the me before she lost her memory?!

"I see, your memory hasn't returned yet."

I don't know how Ayase misinterpreted my distressed expression, but her eyebrows furrowed sadly, and then—

"But it's okay!"

"Hey hey hey"

She suddenly twisted her body on top of me and jumped off the bed—

"Let Ayase take responsibility and make her brother regain his memories!"

The curtains were pulled open forcefully, and the fresh morning light gradually bathed the ward in a color of hope.

"Let's do it one more time, carefully. Good morning, brother!"

Ayase Aragaki, my little sister whom I just adopted yesterday, said this with a dazzling smile first thing in the morning.
