I know in manga everyone falls in love with a childhood someone, but honestly her reason for him is by far the dumbest... Like I hope she stops having a filter of him being a "prince" and instead realizes that he was just a weird kid who did a stupid thing like DRINKING SOMEONE'S MEDICINE IN A HOSPITAL!!!!!!! I'm fine with them ending up together but let it be because of them developing the relationship now instead of her giving him so much extra attention from a VERY stupid unkind thing.
You're gonna make God cry, stop it.They should just become a thruple
