The person who likes me is a yandere.

"A photo booth picture."

"I know that..."

"Take the photo using your usual pose."

"...Who is this person?"

Ah, so I really had to complain about this...

"I asked someone for help. The poses of the Aragaki siblings couldn't be captured by one person alone."

"help……"

Ayase's eyes widened. Yes, that's it, that's it! The arcade staff had the same look in their eyes.

"What else could I do? It was such an emergency, and she was the only one willing to help. It was the best course of action."

"The most appropriate method?"

That's right, the person I'm holding in my arms, with a bright smile on her face, is a life-size standee of the super popular model that every high school girl knows... The printed photo booth picture is filled with pictures of me and the standee.

She's beautiful, stylish, has a great figure, and never gives me any criticism—she's the best partner. The only downside is that she's taller than me.

"What is this?"

Next, Ayase picked up a cheap imitation leather belt. It had a picture of a spoon stuck in a snow-capped mountain printed on it, with the words "Certificate of Passionate Himalayan Summit Climb" attached.

"Could it be... that they went to eat?"

She seemed to already know the correct answer before she even asked.

"Yes, I've already eaten."

"one person?"

"Thank goodness I didn't eat properly during the day and night."

"So you went to eat alone?"

"The store manager had the same expression you're having now back then."

The store manager even considered increasing the portion size of the "Heartfelt Earth" dish.

"So, what is this?"

Ayase picked up a card third. It said "New Record Achieved" printed on it.

"This is proof of setting a new record. It says to take this to the service desk at the science museum, and they will mail the medal to you later."

"Ah, Ayase saw it. From here, you can see a lot of flashes of light in the park. I was thinking that someone would be doing that so late at night, and it would cause a disturbance to the neighborhood..."

That person was me.

What is the new record?

"84444"

"...It must be broken."

I think so too.

Ayase's kick was truly deserving of the title of the strongest in Kanto; Kurobe's weak kick, which couldn't even defeat me when I was exhausted, was simply incomparable.

"Then, a really loud motorcycle sound came from below, could it be that...?"

It's a long story.

"I also heard roars coming from below..."

"Well, it's still a long story."

"........."

Ayase looked at me with an expression that said, "So many things have really happened." Then, Ayase once again spread the three items out in front of her like playing cards.

"…………hehe"

Then his shoulders began to tremble.

Don't laugh.

"Why aren't you laughing? It's so late, what are you doing..."

Her voice trembled as her shoulders moved.

"What on earth are you doing...? Are you stupid...? Hehehe."

"I think so too. But it's all thanks to all those silly things I did that I was able to find this place. Dr. Miyazaki is really amazing!"

Dr. Miyazaki once said that living as normally as possible can help restore memories. Ugh, for Aragaki Asahi, going on a date with her sister is absolutely agonizing.

"After I carefully followed the date procedure you described, Ayase, I actually found this place."

I've finally found you.

"Seriously...you're so stupid...idiot..."

"Wouldn't Ayase's brother do that?"

"...Stop talking nonsense, you idiot."

As Ayase finished speaking, her shoulders trembled even more violently. She lowered her head, clenched her fists on her knees, and tried her best to close her eyes. She looked so strong that I pretended not to see the tears that were already streaming down her cheeks.

"Sorry……"

Ayase said with tears in her eyes.

"Ayase seems to have done something really outrageous..."

"..."

"It seems Ayase can no longer call me 'brother'... I'm sorry... I'm sorry..."

"The one who must apologize is me."

"...Huh?"

This is the first time I've ever seen Ayase cry.

Ayase was always smiling, ever since the day I woke up, ever since the day I forgot about her. She was always smiling, even when she was talking about how her parents died, when she rushed towards me, and when I rejected her—even when she shouldn't have been smiling.

It wasn't that she wasn't sad, it wasn't that she wasn't heartbroken, but in her heart, I was her only family in this world. How could she not be afraid, how could she remain calm after being forgotten by me like this... but she kept smiling.

Of course, the one who's most heartbroken is my older brother.

Ayase once said something to me in the park. Even though I was the saddest, Ayase, the second saddest, kept smiling at me. How strong this child is, how deep her feelings are.

"I'm so sorry, Ayase."

And why didn't I notice this? I'm always so self-centered; when I'm emotionally unstable, I start to get angry and vent my frustrations indiscriminately. Why can't I be a little gentler?

When I woke up, for the first time, I felt disgusted with myself after the accident.

Thank you, Ayase.

I think this is probably the first time I've ever expressed my gratitude to Ayase.

“…I said, Ayase.”

I sat quietly beside Ayase.

Ayase kept her head down and tried her best to close her eyes.

"I don't know if I'm really your brother, and I don't know when I'll change back."

This is my sincere and genuine feeling.

I still don't know who I am, or if I am Ayase's brother.

Even so.

"...Even so, let's continue to be together from now on."

I don't want to lose Ayase. I can't hide this feeling right now.

Let's live together in that house, just like before.

—While searching for memories of the past.

— Creating new memories.

"Let's become brother and sister."

Let's be family.

"........."

It was obvious that Ayase was straining her shoulders, but she still couldn't lift her head. It was as if... even the slightest movement would cause her balance to crumble.

I reached out my hand to Ayase like that...

"------"

Immediately, my face became burning hot as if it had exploded.

Hey, what am I doing? Don't be shy at a time like this.

I hesitated before moving my right hand, but it still kept shaking.

No, I can't take it anymore. Forget it, I'll just give up. Fine, I guess I'm a coward. Facing Ayase… facing such a cute girl, I just can't bring myself to touch her.

so--.

I reached into my pocket and pulled out a white handkerchief.

This is the handkerchief that has always bound Ayase and me together. I placed the crumpled handkerchief on Ayase's head and gently unfolded it—

"Good boy... good boy... good boy..."

He stroked Ayase's head three times through the handkerchief.

Just like that, I was already drenched in sweat.

Okay, all done.

I've already taken care of everything, is that all? Asagami Aragaki.

"elder brother!"
