An immortal carrying out his tribulation duties descends to Earth in search of his liberator. Now existing in the world of mortals, Chan'Er finds a royal convoy being ambushed in the forest. Without hesitation, he jumps in to protect the prince, but something else gets in his way.

Now Prince Xingyi thinks owes a stray kitten his life and takes the innocent-looking animal back home.

While waiting for his powers to be restored, Chan'Er has no choice but to go through Prince Xingyi's royal duties as a lap kitten. And while Xingyi is a perfect example of royalty in public, Chan'Er has the unfortunate fate of seeing the prince's hidden fondness for animals... particularly felines.
