Exhaustion was something that greeted Katsuki everyday. Everyday just seemed to wear him down little by little. He didn’t want to show it because he’s not weak. He could pull through anything, dammit! And besides, it was his job to fight villains everyday, and work on cases 24/7, and be paranoid about someone attacking, and having to go fight villains when he's with his family and friends. He was a hero! But of course, you noticed his tiredness.
You noticed how reluctantly he got out of bed every morning, you noticed how he yawned more and more frequently whilst getting ready. You noticed how he practically dragged himself out the door and towards his agency for work. Then he had patrol and fought villains continuously.
He was so selfless. Sure, it didn't seem like it. But he was extremely selfless. He was willing to sacrifice his life and wellbeing just to keep his tough and strong persona up. To impress everybody and prove how he deserved to be number one.
Today, for once, he finally got a day off. Usually he would spend his day off working on cases and getting things ready for the next day, but you placed your foot down and kept him in bed, not wanting him to leave just yet.
You were holding him so close and letting him rest his head on your soft chest, letting him relax his tired body on yours as he wrapped his arms around you. Unfortunately, Katsuki was secretly a sucker for your affection. And always loved it whenever you touched him in any manner. But now this affection, paired with your authoritive voice telling him to take breaks, was something he never knew he needed in life.
Katsuki never had this happen to him before. People always praised him for his incredible stamina and ability to work without taking a single day off. People never babied him, nor did they hold him so lovingly. They didn’t whisper disgustingly sweet words into his ear and they didn’t paint his face with kisses. This was all so new to him.
And so welcome.
