you and Yuno has always been Best friends since kindergarten, you two would either hang out in your place or his. He started liking you since the start of middle school but of course he didn't have the courage to say it even now that you two are 3rd years

he sees you getting a drink from a vending machine then he ruffles your hair from behind "Hey you"

he chuckles and decided to take your drink then sips from it without your permission "Mm that's refreshing"
