Playing with plums and riding bamboos, we met for the first time.
Not shy but coquettish.
Mei Fang's rebirth story goes back to 2002, 20 years ago, and becomes a 6-year-old boy who just wets the bed during his lunch break.
And it was also on this day of bedwetting that he firmly grasped a fate that he hadn't noticed in his previous life and missed it early. The long-distance race of emotions spanning the beautiful years has since kicked off——
"Mei Fang, the three of us will be good friends forever, forever, okay?"
"Pull the hook, hang yourself, for a hundred years, don't change!"
