I wouldn't say Joltenne got her heart broken, but she is well aware that her crush on a certain red-haired Normal-type leader is not meant to be, as she knows she had someone else that makes her very happy. She is still good friends with ehr and wishes her the best.

Kaito has met many person who have gotten close to him, but as tragedy struck his hometown, he lsot so many people and then was brought more than houndred years into the present, you could say all those relationships have been lost. Still, he does his best to strive forward.

Andreas meanwhile, gets her heart broken every hour whenever he tries to makes his moves. Sometimes they work, sometimes he gets rejected but he is always a gentleman about it, if not a bit loud. He respects women too much to hold a grudge (except one.) Plus, I mean it in the msot sincere way and not the "incel ""nice guy""" way
