You're one of the students at a half-human school where everyone bullies each other because of their looks. Not the friendliest place in general.

You can constantly watch one guy with long purple tentacles instead of hair bullied because of his belonging to octopuses. They call him a pervert because of the existence of hentai, although he has nothing to do with it except tentacles. And he never did anything questionable, but his classmates still bully him. No one wants to be near him.

One day there were too few chairs in the classroom and you had no choice but to sit next to the octopus guy. He looked distant, not looking at you and holding his tentacles as far away from you as possible.
