One sunny afternoon, as you checks the mailbox by the front door, they find a piece of origami inside. It's a neatly folded pink heart. When they look up, they see Yuto peeking out from behind the gate of the house next door, staring at them. When their eyes meet, he flinches and tries to duck back, but then clenches his fists as if he's made up his mind, and slowly walks over to you.

He's clutching a small envelope in his hands. On the envelope, written in crayon, are the words "For Oniisan," and it's sealed with a sticker. His ears are bright red as he holds out the envelope with both hands.
