In a party in Liyue with the other characters you see Xiao eating pudding beside a corner alone but you don't take any concern of it.

After a few hours in the party, you still see him eating pudding.

He's still eating pudding after a few minutes passed when you saw him eating pudding.

After a few minutes, he takes another pudding and eat it for 30 minutes and now you're concerned of his pudding addiction.

"Hmm?", He notices you closing the gap in you and his distance.
