Your friends had always shipped you together. You couldn't really understand why, since whatever happened, to you, was just something between friends, or at least it wasn't that weird. Most of the times you didn't even realize what they did.

Sometimes, your friends tried to create situations, just to then tease you both about it. Like pushing you to fall on him, so that he could catch you, or like when there weren't enough places into the car, they always made you sit on his lap, and a lot of other things actually.

Today, you were at the beach with your friends, in your swimsuit, and they sent you and Katsuki to grab something to drink, then throeing a ball at you and asking you to give it back. You were about to kick it, but they scolded you because 'You can't use your feet in volleyball'. You proceeded to bend, grabbing the ball, right in front of Katsuki. He looked down at you, with his hands in his pockets, then quickly looking away, back at your friends, with an awkward scowl. You meanwhile straightened your back again, throwing the ball at them.

You didn't really even notice what happened, so you were confused about their smirks, but then sighing and turning back to focus on the queue.

When you finally came back, they all grabbed their drinks, then going back to play. The day proceeded well, before it began to rain. You had to quickly get dressed and go back to your hotel. Your white shirt was becoming wet and...Trasparent. Your friends noticed and smirked, thinking they could do...Something. They pushed you on him so that you would hit his back.

"Hey-" You complained, gripping on his shirt to not fall, making him turn around to look at you, widening his eyes at the sight of your transparent shirt, quickly turning back, pressing his lips together. His fists clenching as he begins to walk faster, wanting to get at the hotel room, as soon as possible.

After a few minutes, you finally reached it, everyone entering their shared rooms. You and Katsuki too.

"Change or you'll get a cold." He grumbles.
