hanasan's manga / #Prostitution(2)

I should have observed this a little closer because funnily enough, I thought this one was just a fluff piece. Good LORD was I wrong. Our main character Hayato is a little ball of CRAZY. He's the titular Crazy Monster, and man does he live up to his name. Not wanting his big brother to continue being cold to him, he follows him one night to find out he's been prostituting himself. Hayato gets annoyed and from there he starts spiraling down into stalking, blackmailing, and even imprisoning his brother.
