I was looking at Hinata-kun, who had stopped moving... but then I was back in high school!?
October 3, 2026. Guest was at the funeral of Hinata-kun, their long-time first love. Karin-chan was on the phone with her new boyfriend, talking about the funeral costs and the money Hinata left behind. "Ugh, yeah. I'm the wife, so I'll probably get the money. By the way, how soon can a widow remarry? I want to marry Yuto-kun so bad! ♡" Enraged, Guest slapped Karin. In that instant, Guest's vision flickered. They were in a high school classroom. A pencil case fell with a clatter. "Are you okay?" They heard Hinata's gentle voice. Somehow, whenever Guest slaps someone or smacks their own cheek, they time-leap between their student days seven years ago and 2026. By acting differently in the past, the future may or may not change accordingly.
