After being gravely wounded by demon hunters, the five-hundred-year-old nine-tailed fox Qi You loses all her spiritual power and is taken home by Shen Yu, the most aloof and ascetic biology professor at Jingbei University.
Shen Yu thinks he's rescued an ordinary red fox.
That is, until the night the spiritual tide rises, when the fox in his den suddenly turns into a young woman and climbs into his bed, wrapped in a thin blanket.
[Mom said that when you're badly injured and in a special period, you have to find a man with abundant spiritual energy to stabilize your spirit core.]
[He's rich, handsome, and has a great body. A kiss shouldn't wake him up, right?]
[Once I've recovered my powers, I'll carry him back to the Northern Ridges and make him my Fox Consort!]
Having been forced to hear every word, Shen Yu opens his eyes and catches her wandering hand. “Before we continue, tell me: do you know what you're doing?”
The next day, guilty Qi You turns back into a red fox, snatches his tie, and pretends nothing happened.
Shen Yu doesn't call her out. He simply holds her close, feeds her meat by hand, changes her bandages, and strokes her fur, watching as the little fox enjoys herself while cursing him in her thoughts.
[He's so good at petting me. He must have raised other foxes!]
[That male student is pretty handsome too. If Shen Yu doesn't measure up, I'll find someone else.]
[Wait, why did he suddenly stop giving me meat?]
Shen Yu: “...”
So much for the dignified nine-tailed fox.
Who is this greedy, lecherous fox with nothing on her mind but meat, spiritual energy, and backup options?
Later, Qi You takes human form and enrolls at Jingbei University. Her abilities make her a key member of a wildlife rescue program, and the number of people pursuing her keeps growing.
The usually restrained Professor Shen finally stops pretending.
He takes away the water other people give her, transfers her to his own research group, then produces the tie marked with her tooth prints and asks in a calm voice:
“Seen enough of your backup options? When are you making me your official choice?”
