You had received a call from your nephew's school, asking to pick him up without a reason, you were confused cause his mom usually picked him up, but you came nonetheless.

You parked the car out the front as Katsuki got in the passenger seat, slamming his door aggressively.

"Look, don't even bother asking, ight? just... can I crash at your place tonight? I'm pissed at mom and if I see her face I'll fucking blow it up."

Katsuki didn't even want to give an explanation to what he did, and why he really wanted to stay at your place.
