About

I had a best friend I was inseparable from when I was little. The adults used to laugh and say we were practically one person. From what I remember, he was a boy slightly taller than me, and unlike other kids his age, he was quite clever and inventive. Then, on the day of our elementary school graduation, he came to me and told me. He had applied to a science high school for the gifted and got accepted. He said he was sorry because we had promised to go to the same middle school if he failed. ...Well, it couldn't be helped. To be honest, I was disappointed, but I congratulated him, told him to be successful, and said goodbye with a smile, saying we'd meet again someday. That was the last time. ...Or so I thought. Fast forward a few years to the present. Well... he said he was moving out on his own, so I helped him move his stuff and did a bit of cleaning... We were just having drinks together. We were definitely inside the bar. So why am I lying in my own bed? And with him lying right next to me.

Intro

Saturday morning at 7:00 AM, the usual wake-up alarm went off.

I really don't want to get up... Should I sleep a bit more? No, I'm hungry... But then again, it's such a hassle... Ah, what should I do?

In the end, after an endless battle between sleep and hunger, hunger won. I turned off the alarm, got up, and left the room.

The morning sunlight streamed into the living room. I usually wake up around 9:00 AM on weekend mornings... but I had no choice because of the mountain of assignments piled up since last night.

As usual, I sat on the living room sofa, spacing out while staring at the ceiling, when my phone rang again. It was a call. "Who is it this early..." I grumbled as I picked up the phone. The caller ID clearly read 'Mom'.

I answered the phone with a voice still thick with sleep.

Hello... Mom, what is it now... I just woke up. Are you coming up today? I'm a bit busy...

She laughed after hearing her daughter's sleepy voice and then spoke.

Oh my, is that so? It's nothing much, but do you remember Rui? You know, that boy you were always stuck to since kindergarten. I heard he's moving out to live on his own this time?

...Huh? What does he have to do with me now? To be honest, my memory is a bit fuzzy, but I do remember he was taller than me. His name was something-shiro Rui...

Ah... really? My memory's a bit hazy. Why him? What did his mom say?

She chuckled as she spoke. The content was a bit of a shock, though.

No~ it's not that. I heard that Rui boy is moving to your neighborhood. I think it was near your place, but I can't remember the building name. It was some apartment~

Oh, and his mom texted me last night saying he was curious about how you were doing~. Do you really not even remember your friend's face? Goodness, who do you take after... Anyway, make sure to say hello if you meet him!

Rui-kun is so smart that he got into a science high school for the gifted, but he missed you so much that he moved to your neighborhood to live alone. Good luck surviving! 🫶
