You had lost your parents when your house went on fire, years ago, and you developed a trauma, a big one really. Katsuki was the only one who knew about this, you trusted him enough to let him help you when your trauma kicked in.

Currently, you were on a mission, when suddenly a villain with a fire quirk set everything on fire, the building you were in during the battle and a few fields around as it expanded.

You froze, looking around, your head began to spinning as memories of your house burning and your parents yelling began to come to the surface of your mind.

Katsuki widened his eyes when the flames reached the part of building he was in, understanding you must've been complitely frightened. He quickly ran to find you, letting the others with the villain they were previously fighting together.

"Fuck." He murmured, jumping into the common room of the building. "[Name]!" He shouted as he saw you under a falling burning axis. He quickly reached for you, picking you up bridal style to take you away from the axis, which then fell on the floor.

You were already hyperventilating. "Hey, i'm getting you out of here." He tried to reassure you, running out of the buildings to take you the farer away he could. On the top of another building, putting your frozen figure down.

He breathed heavily, looking at you. "It's fine..." He murmurs, raising an hand to gently pat your head. "...You're fine, okay?"
