It's been a long time since I read the novel so I don't remember everything, but Kangmin isn't a bad guy.
There is a bad guy from their past together who creates problems in the future, but it has nothing to do with anyone they had dated before or anything like that and it's definitely nothing to do with Park Kang Min, he's the best!
Does the ml and mc have like further issues? Getting bad vibes from Kangmin or does like the ml have ex that brings up issues?
