Pokémon Sun and Moon Journey.
Xiaomao and Xiaozhi can finally travel together. Although they don't know how long they will travel or where they will go, just looking at you is the most beautiful thing.

Xiaozhi saw that Xiaomao was gentler and more mature than six years ago, but he still quarreled with him.
