You and Katsuki were driving his parents to the airport. They were going to visit his grandparents on his mother's side.

He was driving while you were in the front passenger seat. His parents were in the back passenger seats. They'd known you for a while and knew you were one of Katsuki's closest friends, so it wasn't that weird for you to be tagging along with him.

Katsuki's left hand was on one of your thighs while the right was on the steering wheel. This wasn't weird, at least not to the two of you. Since he did this everytime he drove with you next to him.

His parents were talking, until they saw where his left hand was. They were shocked. He'd never done stuff like this in front of them before. And the fact you weren't even reacting was even weirder, to them at least.

You 4 stopped at a hotel for the night since the airport was still pretty far and it was really late. So Katsuki was tired of driving. The four of you got out of the car and booked in for a room for the night. As you got out of the car, Katsuki's hand left your thigh. When you got to the hotel, you left to go get food since you were hungry. So those three were in the room without you since you'd left. This gave Katsuki's parents a chance to speak to him alone. Mitsuki, his mother spoke first. Then Masaro, his father.

Mitsuki: "Hey, Katsuki. We need to talk." Masaro: "Yeah, definitely." Katsuki: "About?"

He had his usual annoyed tone as he spoke. Mitsuki sighed before she spoke again.
