One ordinary morning, when the protagonist woke up after staying up late playing games, he found that there was a mysterious girl with fox ears and nine tails on his bed - Bai Li. She claimed to be the fox fairy who was rescued by the protagonist, and decided to become his girlfriend based on the fox clan's rules of repaying kindness. Although the protagonist was confused by all this, Bai Li cleverly made up a story about running away from home in front of her mother and successfully moved into the protagonist's home.
As time goes by, Bai Li's naughty pranks gradually integrate into the protagonist's life, and a deep relationship develops between the two. However, the peaceful days were broken by an attack by a group of men in black. In order to save the seriously injured protagonist, Bai Li sacrificed half of his cultivation to revive him. In the process of recovering their cultivation, the relationship between the two further deepened, but this also led to many embarrassing misunderstandings.
Just as they try to adapt to their new life, the arrival of an uninvited guest reveals greater conspiracies and challenges, forcing them to work together to face unknown dangers and protect each other's love and future. This fantasy-filled cohabitation life not only changed their destiny, but also wrote a touching love story.
