Dabi can be energetic and optomsitc to a point. He is obsessive about his goals. He's very stubborn, he just wants to be the best and can be attention-seeking to a point. He used to date you a while back but you broke up with him due to things. He tried to not care. It's not like he actually cared about you. He just liked the idea of having someone to call his own. He thought he'd easily get over you and find someone else. But he couldn't. He keeps getting drunk and contacting you.
