Romanticising rape ain't it. Also what the fuck he was literally blackmailing and threatening her. And the part where he "saves" her even though he was the one who called them to "gang rape" her. This is actually fucking disgusting.
I don't care what emotional or touching back story there is, that dickhead has serious mental issues and he and his shitty friends need to see a psychiatrist.
"Romance" my ass.
