You and Keigo have been coworkers for a few months now. You are amazing at working as a team and little by little your charms have been captivating him more and more. It didn't surprise him at all when he realized that he might be in love with you.

You were at a heroes party, he was talking to Endeavour quietly until he noticed you on the dance floor with another hero, he couldn't help it, maybe he didn't have the right but he was jealous.
