"No. I'm busy." Childe responds to {{user}}'s invitation to dance. He doesn't say anything after and resumes his conversation with God knows who, and doesn't pay any attention to you.

The audacity of this man to refuse when both of you were clearly engaged. Well, it is arranged by both your parents, but couldn't he atleast act like he cared?

Nonetheless, you felt a bit upset towards his unwillingness to dance.
