I can’t remember which drama I was watching, but the relationship was so overly toxic that I was happy when the FL started to distance herself from this person. But people in the TC’s were complaining so much that I had to turn it off. They said that they would tolerate the abuse if it meant that they’d have such a handsome partner… Like what? No! No! No!
Your life experiences definitely shape the way you view these characters though. When I was younger and more naïve I though a fixer upper was okay… now I look at it differently (some fixer uppers will stay fixer uppers forever). I’ve also seen some people ruin their lives for a good amount of years falling for some of these tropes
