Mi Ya, an ordinary girl, has lived in a mountain village since she was a child. She has a kind nature and harmonious neighbors. One day, while going down the mountain to collect pigweed, I accidentally encountered the strange beast Gray Tiger. After fainting and waking up, the Gray Tiger was gone and no one knew about it. After growing up, he left the mountain village, met two companions on the way, and traveled around the world together. Along the way, she has seen all the good and evil in the world, and has experienced love and hate. She will no longer talk about right and wrong. What she sees with her eyes may be an illusion, but the choice she makes by following her heart will not make her regret it.
