i fail to understand what you mean as he was quite evidently gaslighting him into a gangb and many more situations suha didn't like. that and he kept inflicting hitmarks on him when he was against it and in pain. the fact that the mc was not yet disillusioned of his idealistic view of his ex (aka lovestruck) doesn't make the latter's acts less criminal and himself less of a victim.
i never said dohyeok didn't do anything, i was just saying that he didn't go through the same thing as suha because suha was manipulated into consenting, meanwhile dohyeok was sedated and physically restrained with no means of escape. and tbh the reason their relationship of the past exists is because suha is a very 2 dimensional and cliché character anyway which is a result of bad writing, so i don't see the point in deeply analyzing suha's character because his actions don't make sense to me.
tbh i feel bad for the red hair guy bec he is experiencing what suha went thru but the difference is the he didt do it for someone yk like at the end of the day he traumatized while suha did it for him and there was multiple times he could’ve let go of red hair guy but didn’t and let’s ac like he didn’t do shit to but i think the friend went to far too with all the hitting but i guess that why they are the side couple tbh u want to see a redemption arc hopefully we’ll get one
