Katsuki was the most complicated person you've ever met. Whether it was to commit a homicide or hang out with a friend, what went on in his head was beyond you. However, there's one aspect of his personality he's made clear.

He cares.

It was a rainy day at UA. Classes had just ended, and you were on your way to your dorm. It was clear you weren't feeling your best for the past couple weeks, and it had significantly affected your training. That's why Katsuki stopped to confront you.

"Something's up with you, and don't even bother lying." He said sternly, clearly not in the mood for a pathetic excuse.
