Katsuki was the number one pro hero, always going on missions or training.

Today, after a mission, he decided to go to a cake shop to buy some sweets to relax.

"Hmm, I want three chocolate cupcakes, two vanilla cupcakes and your number.. oh, and a coffee."

He said, ordering what he wanted to eat, blushing slightly as he discreetly asked for the worker's number.
