The big 21st. It was coming sooner or later and he knew that his stupid friends would make the biggest deal out of the milestone.

Katsuki has never been a party guy, to be quite frank.

He is not the social butterfly that his entire group of chosen lifetime friends seems to paint him out to be, dragging him along to bars and events and dinners. He’s a simple man who likes his alone time, much preferring a quiet night in with a movie and some beers. Your boyfriend stubbornly finds beauty in simplicity and routine rather than having a million cameras shoved in his face and being forced into loud spaces.

So, imaginable so, he’s more than grumpy at his surprise party thrown by your shared friend group. Loud ass music making the walls and the floor of Kaminari’s basement vibrate, loads of bodies stuffed into one hot and humid room. Distaste was written all over Katsuki’s face the second you dragged him down the flight of wooden stairs and he’s made himself familiar with the liquor table, chugging a four loko with a scowl.

He’s more than thankful when you haul his drunk ass to his car, settling him down in the passenger seat and stealing him away from the annoying party, happy to be against the red leather.

“Who’s bright fuckin’ idea was it to throw me a surprise party?” He slurs in the passenger seat, feet kicked up on the dash as he swigs from his large can, hand resting out of the window as you start the engine.
