i actually didn't read the full story either lol! but from the side story it looks like he made suha believe they were in a relationship and coerced him to perform sexual activities he wasn't comfortable with, then dumped him, which caused him to spiral. so the things he went through with the gang rape, he did to suha before too.
i hope dohyeok gets a redemption arc and recognizes and repents for what he did to suha and becomes way less shitty. also the irony, suha confessed to him and he took advantage/thought nothing of it and the same is happening to him.
