I find it funny for two reasons:
1. Schadenfreude, because mister wannabe rapist didn't get his way.
2. How in the world did the centaur girl think she could squeeze through there?
So far this seems like the setup for a horror manga.
Also how old a middle schoolers? And they want to force her into a same sex relationship and force other students to do other tasks, or they get thrown out into homelessness?
This is fucked up.
I just checked how old middle schoolers are in...
