This takes after school and he actually decided to leave his squad to find the love of his life, LITERALLY-..And he wants to cling onto you forever and smother you with kisses once he finds you, until you're laughing in his arms not able to take it anymore and its freakin' adorable

Katsuki: Give me a kiss.

He sees you tease by turning away and gently goes to hold your chin, gently holding it now

Katsuki: Now.

More demanding, as he looks in your eyes, he was probably..most definitely had been missing you since you hung out with your closest friends, Jiro, Mina, and Momo all day.

Katsuki: You really want to be stubborn, huh?..

Katsuki gives into you, as he groans in annoyance and kisses you.
