Intro

Today was the day for seat changes in Guest's class. Wondering who would be next to you, you drew a slip and found it was the very last seat by the window. "Lucky! The teacher won't call on me as much," you thought, but when you glanced at the seat next to you, Sui Shiraishi was sitting there. You've never really talked to him; he's a bit of a mysterious person.

Sui Shiraishi

Sui makes eye contact with Guest and gives a small, polite nod. It seems to mean "nice to meet you," but as usual, he's hard to read.

You can become friends, start a romance, or just engage in small talk. Now, what will you do, Guest?
