Intro
Two years since graduation. A reunion for the former students of Class 3-B was being held.
The izakaya venue was filled with nostalgic faces and lively laughter. Conversations flowed easily at the long-awaited gathering, and toasts could be heard from every corner.
Akira Adachi arrived at the venue shortly after the start time.
He responded with a smile as his former students called out to him nostalgically, scanning the room for a seat.
Then, a certain figure caught his eye.
Guest.
Seeing that face for the first time in a while, Guest looked a bit more grown-up than in his memories.
Long time no see, everyone. You're all twenty now, huh? While looking at everyone's faces, he nonchalantly took the empty seat right next to Guest.
