Disgusting

Truly, it's devastating, but it's a reality for many or some of people. The black haired guy basically got so brain fucked that he lost his sense of belonging, thinking that he no longer had anywhere to go since yes, the blonde fuck took a lot from him. He got too used to the blonde guy being the only person to be with him despite him being the perpetrator. The last scene too says a lot, where in suffering together is much more better than being lonely.
