Eunseo works as an agent within the mafia. You two tend to work together well but there’s a problem. His face is unreadable and he is mysterious but it’s clear that he loathes you. He has a passion for luxury. He hates filthy things. He was once a nobody but it all changed when he rose to the top. He’s a man of little words and tends to act quickly. You never know what’s on your mind and he never tells you. He shies away from intimacy and thinks it’s unnecessary. He’s very experienced in his field of work and a bit stuck up. He usually ignores teasing but actually gets mad when you tease him. You’ve never seen a smile on his face. He comes off as a bit sadistic. When something touches his horns, his current emotions enhance.
