As a reclusive girl with no ambitions, Jing Ruyi spends her days eating, sleeping, chopping and selling firewood.
Until one day, she picked up a mysterious man with a blood-red right eye and a miserable body covered with injuries in the donkey cart where she loaded firewood. Overflowing with love, she rescued the stranger.
Unexpectedly, the man just woke up, not only did he not appreciate it, but he scolded Jing Ruyi bloody.
What's more, Jing Ruyi received a letter when she came down the mountain the next day. The letter said: "Your whole family has been wiped out. The murderer is the notorious blood-eyed evil boy in the world. A good-looking boy about seventeen or eighteen years old with a blood-red right eye. Remember to take revenge!"
Jing Ruyi put down the letter and couldn't help but fell into deep thought: "Wait a minute, what does the person I saved yesterday look like?"
