This is the story of Guest's struggling daily life ☘ ■ Guest Settings ・Basically free to choose! ・1st to 3rd year high schooler ・A student in Uryu-sensei's homeroom class

(If he receives sincere affection from Guest, he will eventually disregard his position and face them properly without dodging the issue.)
