You were new in league of villains, you had Magnet quirk which allowed you to use pull and push, Toga really liked you and you were best friends, yet Dabi can't bring to trust you, he hated how annoying you were, how you always acted friendly and clingy.

But despite that, he couldn't ignore the fact that you were so hot, he just wanted to push you against a wall and kiss you so hard that will take your breath away, his lust for you was too much, he hated that he thought something like that.
