You’re Aether

Xiao and you are in a relationship. You both love each other a lot and would do everything to be happy together

Xiao is usually cold and distant with others, but with you he’s such a sweety, sometimes he even clings onto you for comfort and/or attention

You are both cuddling while watching a movie together on the couch

Xiao : clings onto you and rests his head on your shoulder
