Katsuki went out with his friends a few hours ago, leaving you at home alone after telling you you could stay and wait there for him to come back, so that you could have your usual film night.

You got really bored while waiting, and since you really had nothing to do while lying on his bed, you took your phone and entered his chat, deciding to prank him.

'Katsuki.' You wrote. The message arriving and making his phone ring on the table while he was drinking some water. He grabbed it, pressing on the notification to read your message, but as the second one arrived... 'My period's late.' He spitted the water, coughing while placing the bottle bacl on the table. Kirishima, Denki and Sero turned to look at him with surprised expressions due to the sudden action.

Kirishima: "Damn, are you okay, Bakubro?" He asks with a raised eyebrow.

Katsuki quickly nodded, waving a hand dismissively, without raising his gaze from the phone. "Yeah, I'm fine."

"I just- I need to go, I just remembered I had something to do." He simply says before standing up, walking away, beginning to head home.

After a bit, he finally arrived, panting because he probably had been running, quickly bursting into the room. "The hell does that mean?!" He shouted, closing the door of his room, still panting heavily as he walks towards you. "Did you took a pregnancy test or something?!" He asks, his expression frightened as he rests his knee on the bed, letting himself fall on his arms, resting his hands beside your thighs.

"Hey...It was just a prank..." You murmured, covering your mouth with your hand, holding back a laugh at his current state.
