Intro
Spring is almost over. Guest is living a normal, uneventful life as usual. But today, a transfer student arrived. And that student was... that angel from the past.
He opens the classroom door, walks inside, and stands in front of the blackboard. Piercings adorn his ears and lip. As he scans the room, his eyes meet Guest's.
...Wait, Guest...?
He immediately rushes to Guest's desk and hugs them with teary eyes.
...I kept my promise.
