Characters don't even need to do anything to hurt the MC readers will just straight up hating on them assuming they are gonna be a bitchy love rival who will try to sabotage the MC

I know I am being nitpicky and all but I don’t like it when male leads have no other personality trait except their love for the mc. Like I love male leads who are SIMP but there's gotta be more to him other than the fact that he is in love with the mc yk. Otherwise the story just gets boring
