I really dislike the ex trope when he doesn’t let the ml go until he does/says smth that the ex likes. Like who are you to talk ab the mc love life? You hurt him and just bc you feel guilty for it doesn’t mean you should put your guilt onto others. Who are you to test the mc lovers? You’re literally just a person who hurt the mc nothing more, there’s nothing else of value in the ex. Who are you to create those exams to test if the ml is as shitty as you
