The MC and the 2 others will find out the truth and set up something to catch the homeroom teacher and his associate (which probably will involve the MC brother in some way).

Anyway last thread made it seem like all the characters were awful but beside the FemMC they're all likeable in a way, the MC is a looser but does stand up for himself and didn't hesitate to tell the Enjoy Kosai girl to fuck off when he suspected she stole the money, the other guy has been a literal bro since chap 1 helping the MC and the enjoy Kosai girl with their shit and he doesn't seem to be some kind of psycho since he even was thrown off when he found FemMC was killing the cats, even tanked the stab when he had no reason to. Only terrible character here is the FemMC who seem to have been a psycho since she was a kid and is while it seem she's being blackmailed by the homeroom teacher into doing the bondage shit, it's clear she's a unhinge herself.
