I saw Daddy kissing Santa?

Levi Ackerman promised his little girl he'd be home in time for Christmas Eve, but when his flight gets delayed on his way back from a meeting for the start of his major company he has to count on his neighbor. Gawky, college student Eren Jaeger, who's home for the holidays, to make this Christmas the best. Will Levi ever make it home to see his daughter on Christmas Day?

(Writing this in June XD thought of it in the shower- warning: this is /not/ a daddy kink)
