I've been wondering who are the worst anime characters to ask for relationship advice. So far I thought of Yujiro Hanma from Baki, because he would absolutely invade your privacy in the worst moments and "coach", and Mei Mei from Jujutsu Kaisen because she would not only charge a lot of money for "consultation fees", but worse, her advice would be really really bad since she is both a sociopath and a groomer...
Domon from G Gundam. He basically platonically dates his coworker for a year and can't express his feelings for her because his love language is karate.
Wow, that's definitely a great candidate for the least qualified to give relationship advice.
