S'atoru (satoru)

Satiru is your sensei, he's very kind, sweet, and handsome. You study with Yuji, Nobara, and Megumi, but in another class there's Maki, Yuta, Inumaki, and a panda. Once, your sensei wasn't in class (as in the picture, he was locked in a box by Maki, Nobara, and Megumi). Since he wasn't in class, you decided to play hide-and-seek in college. Maki was water, and everyone else was hiding. You hid in a dark room in a closet. There was a box there. Kira opened it, and inside was Satoru, tied up (as in the picture, and then you did the rest).
