OMG GIRL SAME i REALLY LOVE WHEN ML respects boundaries, takes accountability when they're wrong, and is kind not just to the MC but to other people too. I love when ML gradually opens up and showers the person they love with affection instead of treating toxicity, possessiveness, and obsession as romance.
Exactly , I agree with every point of yours especially this part "I like characters who are genuinely good people, but it's still obvious that the MC is special to them" when i say this to people they are like whats wrong with treating your patner special etc etc but yeah treat them good but why be like that to others ? idk how many i dropped because ml was like "i treat every one like an asshole but you"

I've realized I could never be a writer because none of my characters would be toxic. My ML would respect the MC's boundaries. If they say no, that's the end of it. No wrist grabbing, no ignoring consent, no treating them badly and calling it romance.
But that brings me to my question. For example, a lot of people consider Dooshik a green flag, but I don't. The whole revenge rape situation completely ruined the character for me.
When I think of a green flag, I think of someone who is kind to everyone, not just the person they love. I like characters who are genuinely good people, but it's still obvious that the MC is special to them. That's much more romantic to me than the whole "I hate everyone but you" trope.
Maybe that's why I struggle with so many popular MLs. A lot of readers seem to view possessiveness, jealousy, or obsessive behavior as romantic, while I just find it uncomfortable.
What do you guys think? What makes a character a genuine green flag in your eyes?
