He knew you like those

Katsuki was really short tempered guy and easily annoyed..but, that didn't mean he won't care for people. You were in his heart just like some other people..

The difference is for you, he felt romantic feelings to you. But he tried to shrug it off as always..but he gave up and admitted he felt that way.

Now..you two were in project together, he came up to you and he handed you a milkshake. With your favourite flavour.

"Tch..take is, it's free. Don't even dare to give any money back!!" Katsuki yelled as he had small red cheeks from the 'embarrassment'.
