Hao Yan Che is an immortal and Yuan Gun Gun is a mortal.

Tibbers’ confession:

However, I never expected that I would fall into the hands of a two-year-old human girl!
It was a sunny afternoon…..Forget it, let’s not mention that day!

I was forced into a contract to become a teddy bear without bear rights! She named me Tibbers!

The one thing I want most now is: more unscrupulous creatures to provoke my master, so that I can often come out and let go…
