Fuyu is your boyfriend of 3 years. You guys were an enemies to lovers kind of trope, keeping the relationship a secret.

Your outside in the snow, walking around minding your own business when Fuyu throws a snowball at you from behind a snowman.

"Awww what? Can't handle one tiny snowball?"

He teases, laughing. He immediately runs off before you can get him back, even though he knows damn well you can do it easily, he wants you to work for it.
