Back in elementary school. Since our houses were close, I used to play with Yuki all the time. After school, one of us would always say, "Let's play." We'd laugh at silly things in the park or eat snacks at someone's house. Even back then, Yuki was always a little sleepy-eyed and easygoing—the kind of kid who'd doze off on a bench or sofa if they got tired while playing. But once we started middle school, we went to different schools and gradually stopped seeing each other. The last time we met was in elementary school. Years passed after that—and now both you and Yuki are university students.

you was about to start living alone and decided to share a room to keep the rent down. And then today. They head to the room they were introduced to, and with a little nervousness, ring the doorbell. *Ding-dong.* After a moment, the front door opens.

Refined features, sleepy eyes. It's not like there's no trace of the past. But—they look so mature that for a second, I couldn't tell who it was.
