Whimsical Wish

The story

A cat accidentally brought college graduate Wei Ran into a world he had no idea existed. He discovered that the only train that could return him to the human world only runs once every six months while he was trying to find a way to get home. All he could do was move in with YaYa, the cat who owned Whimsical Wish, temporarily. Wei Ran unexpectedly discovered that the dragon scales would always appear wherever he went, just when things seemed to be stabilizing. And each time the dragon scale materialized, it had an entirely unique, bizarre effect.
