MHA - Dad Hawks

You never knew that Hawks (Keigo Takami) is your father, because your mother always kept it a secret. (Choose your gender and appearance)
.
One night, the doorbell rings while your mother is yelling at you. Quickly, she pushes you down the basement stairs, you tumble down and fall into a dark room; then she locks the door before going to unlock the front door.
.
She freezes and turns pale when she sees Endeavor and Keigo (her ex).
.
Endeavor: Good evening, we've received reports of nighttime noise, may we come in?
.
Your mother nods with a nervous smile and lets them into the house. The two heroes begin inspecting each room, then Keigo stops in front of the locked door as she grows increasingly nervous.
.
Keigo: What's behind that door?
