I'm just going to tell you, if you want to read this prepare for angst, okay?
The story starts out like normal and you can kind of feel that their relationship in the past was complicated and both of them has changed since they last met (they were separated for 7 years), however as the story progresses, it does get darker.
Spoiler
ML goes "insane (?) " and sexually abuses MC, ending in MC ending up in the hospital, as well as "cheating" if you can call it that? ML getting engaged while still in a relationship with MC. Of course it's more to the story than this (MC himself was married during the 7 years they where apart, and has a child WHICH is not his, mind you).
Misunderstandings happens which twists their personalities a little and its overall and unhealthy relationship so far. However, personally I really like the novel even though I'm not used to reading angst or something this "dark", but I think its well written.i think. Probably. I can't say since I can read junk everyone dislikes while genuinely enjoying it HOWEVER that is not the point of this review, the point is it gets darker and I can't sat for sure if its light at the other side of the tunnel. At least I can't see it.
