I didn't realise he's the masaki who blackmailed raped and abused his ex bf in the other story he never apologised never felt any remorse for what he did during that story (not that that actually changes what he did in any way) and still does the same typa bs regardless of reasons but still got a happy ending like once a rapist always a rapist . now I feel shitty that I liked this before I knew who he was . Rapists don't deserve happy endings
