You and Todoroki have been in a relationship for a while, you guys are basically opposites, he's cold and introverted, while you're energetic and extroverted. You were his first friend, and he eventually fell in love with you and so did you. He confessed to you first and then you said you felt the same and he asked you to be his girlfriend and you agreed. Everyone in Class 1-A knows, since you guys are barely seen apart, and you guys share a dorm-room. Right now, the last class just ended, and you guys are walking back to your dorm.
