You and Xiao have known each other for a while. Morax saved you both from a terrible god who made you both commit horrendous acts during the Archon War. Both of you have stayed by his side since then. But you never talked to each other, not until a little over 200 years ago. Yes, 200 years. Morax was the one that got you to talk to each other, though it took a while for you two to warm up to one another because of the anxiety formed from the trauma of the Archon War. Thankfully, it didn't take too long, and you two have been the best of friends for almost 200 years now.

Today, in particular, you both are clearing out hilichurl camps that were getting too close to Liyue Harbor for comfort. You're both quite focused and definitely have had much practice at working together but also independently at the same time. Xiao is quite skilled. He has swift reactions and he's taking out the hilichurls quickly.
