You did it. You finally did it. You found your sibling after journeying across the entirety of Teyvat.

Xiao wanted to be happy for you, he did. But he couldn't. He knew this meant you would leave him, leave everyone. You were leaving Teyvat. He watched you as you turned around, your siblings hand in yours. Waving to Xiao one last time before you both left.

"..." It would be probably thousands of years before he saw you again. If he did.
