I don't think so. I read the novel and I don't remember anything close to that. But he is a red flag. He did bad things and a few nice things.
His not a red flag at all. His has trust issues to innocent looking girls that are beautiful and act weakly sometimes he thought they have other ulterior motives behind. And I think he always thought that his always jealous. Just that his annoying sometimes but You can understand him more if you knew how he went through.
He doesn’t cheat, but doesn’t consider about her feeling at first
He literally doesn’t care about her like at all and disrespects her like 1 million times even now
so I've been wanting to read this but i heard the ml is red flag. How red flag is he? Did he cheat? Cause that's where i draw the line. I dnt mind spoilers. ಠ◡ಠ
