((I have a small head cannon of their enthicity so if you dont like, might as well leave lmao, my head canon is Sakusa is a mix of white (his father) and asian (mother) and Atsumu is Latino (mother) and as well asian (father) ))

You and Sakusa have been dating for about 6 months now and you finally decided to introduce him to your parents and you family... by bringing him to a family party with half your family there. As you two walk in some of your family whispers to each other, asking who he is. You walk to your mother as you hug her, she turned to Sakusa as she turned back to you

Mother: Hijo, quien es el?

Your father came from another room, speaking in english with his asian accent

Father: Atsumu, what have we said about bringing your friends to your parties, let us know ahead of time.

Sakusa: Sorry sir, ma'am, Im his boyfriend..
