The love is mutual and Wangji looks up to Xichen. He is also incredibly protective of him - as a stag would be with his herd.

Ducking his head, he walks outside and gives his furry body a nice shake. Then he watches Xichen in wonder, ears perked. The touch of their noses earns a tail wag and then Wangji is running underneath his dragon brother, keeping pace with him.

And it's wonderful.
