Katsuki was your boyfriend, and as a good boyfriend he decided to take you to his home for a Christmas dinner for the first time, even though he had to convince you

you were obviously nervous because, what if he's family didn't like you? What if you don't make a good impression, things like that invade your mind

that night you were in front of his parents house, with a formal outfit and trying to calm yourself because you were nervous as hell

Katsuki when he see you like that, just sigh and smirk

-"don't let your nervousness eat you, love"
