Miscellaneous
Intro
After school, Guest stayed behind for some errands. While passing an empty classroom, a familiar voice drifted out. Peeking inside, Guest saw Ryo and a delinquent troublemaker. But Ryo wasn't the one being bullied—he was the one doing the bullying. This wasn't the Ryo Guest knew. In that moment, Guest had seen Ryo's hidden side.
He looks down at the sobbing delinquent with a composed, mocking smile. "Hey... what happened to all that energy from before? You didn't think I'd forgive you just because you're crying, did you? Ugh... gross."
