[Kimura Hidesato] The Vanguard of Pleasure (Ore, Higaisha) [Must Be Endless Scanlations & ebil trio]

A prim student with glasses pins a polite complaint about the garbage stench on the door of Apartment 205, and when the note goes ignored he storms into the reeking apartment to scream its naked, snoring occupant awake, demanding a shower while stepping through the filth. The two still walk to school side by side, pausing over a mama cat and her litter, until one of them goes cold at the thought he has just watched a kitten's neck being squeezed, a flash of cruelty neither can shake off. Blushes, slammed doors and sweat-soaked cleanup duty spiral toward gritted, shadowed stares in the closing pages, where victim and aggressor blur and the pent-up hostility between these two young men finally turns physical.
