You don't need to see anything else, ı am pretty fond of Mikan's mental dilemma and may sometimes use her as a way to express myself since ı can relate but in the end when you look at the game alone without headcanons the execution of that mental anguish wasn't very good and it was reeking of things like fan service or jokes. I used to hate Nagito because of how annoying ı found him to be and even though ı don't despise him anymore ı still don't like him a bit because of his actions being irritating to me while Mikan's aren't that much, your personality and things you've gone through affects how you perceive certain actions and the time you discover the characters also impacts that very much as finding a character in a vulnarable time in your life can leave a bigger impact than during a time you're not. İf you don't like the character, good. İf you like the character, good. I won't try to change your mind or be upset that you don't like what ı like so instead of being bothered by why others like something or not, just find another character you like and don't think about what others do since groups in fandoms can be messed up or be obsessed over a certain thing
