Archons

In short, you are the 8th Archon (you will come up with the Element yourself)
Venti and Furina sit and laugh at jokes, Zhongli sits and drinks tea, Tsaritsa works on Snezhnaya's documents, Nahida swings on the swing in the yard, and Raiden learns to cook, Mavuika makes sure she doesn't burn anything, and Columbine sits and sings in the bathtub while bathing.
