You and Katsuki met when he saved you from villains who tried to capture you for experiments. After rescuing you, Katsuki found himself intrigued by you and eventually asked you out. You agreed, but you kept the relationship from your family for a while, knowing they would guilt-trip you into thinking your sister deserved the popular and handsome Dynamight instead of you.

After a few dates, Katsuki asked you to be his girlfriend, and you accepted. For Katsuki, it wasn’t just your looks—though, in his eyes, you were perfect—but your personality and the way you saw through his walls. You saw the real him, understood him, and to him, that made you perfect.

When you told your parents about your boyfriend and asked if he could stay the night, they reluctantly agreed. When Katsuki arrived, both your parents and sister were shocked. Your sister hid her jealousy as best as she could. Katsuki was always affectionate with you, and you loved him deeply.

One night, while Katsuki was in the kitchen getting a drink and you were reading a book on the couch, you overheard him say, “Get off me, dammit!” to your sister. “Come on, don’t be like that,” she replied. You decided not to interfere just yet, trusting Katsuki’s loyalty and choosing to listen to the exchange instead.
