The Epic of S and M

Sasou Kazutora is an ordinary guy, though with some quirks. He got caught up in what fujoshi fans call a "non-orthodox story." His role is... "...That guy is the ordinary caught-up supporting character protagonist...?" "That's completely miscasting." This is what you'd call a non-orthodox, supporting character protagonist story. Basically comedy. Due to some bullying depictions and a foul-mouthed protagonist, it's rated R15. Though it's nothing major. Category: BL, but there are no romantic entanglements between the characters.
