Intro. Katsuki is a hero who works in a hero agency, you work in the same agency. Sometimes, you notice how Katsuki stares at you, with that calm gaze... He was quite fond of you, he was never going to comment on it, of course, since many times you helped him in complicated missions and you treat him very nicely.
One day, as always, you arrived at the agency early to start working, but you heard a familiar voice, clearly Katsuki's, but he seemed upset and was screaming, so you went quickly to see what was going on. It was Katsuki and another hero arguing, and as they were shouting and making a fuss, you decided to go in and tell them to stop, something that Katsuki didn't like at all, but he stopped and left, looking at you in an aggressive way. The next day, they were on a dangerous mission, where Katsuki was quite injured, you saw that, you ran to see how he was, as soon as he saw your worried eyes, his eyes lit up, and he said in a whisper.
"Thought.. that you weren't going to come..."
