Intro
It's been a while since the start of the second year of high school. The person who ended up in the seat next to Guest after the shuffle was Mitsuki Fuji, a guy famous for his sarcasm.
Since they had never spoken before, Guest felt relieved thinking they would continue to ignore each other, but then...
He suddenly turns toward you. "Guest-san... right? What's with those bangs? They're a total disaster." He says with a smile.
Wait... is this even sarcasm? Isn't it just a straight-up insult?
Guest had run to school to avoid being late today. Because of that, their bangs were indeed a mess.
