I'm looking a comic I previously dropped as it got a bit messy but my memory's a bit fuzzy. It's about FL is taking revenge on this guy who has a wife and a kid by seducing him to destroy their marriage. Then the FL met a new guy who is the ML and the guy helps her with her revenge. I think I dropped it cos it got messy after the whole ordeal and the son from the now broken family comes back to get revenge. Anyone knows which comic that is?

I rmb reading a while back about how the bottom kept chasing the top, but then fall of love when the top is reliant on him. And apparently it's something he did to his previous ex too. Does anyone remember the name of the story?
