[Emotionally steady, laid-back, jack-of-all-trades young Daoist] x [Decisive, aloof, calculating Eldest Princess]
Xie Longxing is the Eldest Princess's cat, and she thinks her owner, Fang Jinhen, is an absolute nuisance.
Every time Fang comes home at night, she holds Xie and pets her for ages. She scolds her whenever she goes out to play, and insists on sleeping with her every night.
Xie Longxing runs away, but as soon as she gets outside, she's hit by a carriage.
When she wakes up, she finds herself a young Daoist nun living deep in the mountains. While out gathering herbs, she discovers a badly wounded woman lying in a bamboo grove.
The woman is covered in injuries, yet breathtakingly beautiful. To Xie's surprise, she's none other than her owner, the Eldest Princess, Fang Jinhen.
Xie Longxing has no choice but to carry Fang Jinhen back to the Daoist temple, break the iron chains, feed her rice porridge, and treat the Gu poison.
Xie Longxing really likes Fang Jinhen as she is now. Lying in bed, unable to move, she's like a wooden doll. She can't spend all day hugging and petting Xie, so Xie can go rub up against her whenever she feels like it.
Fang Jinhen finds the girl who saved her rather strange.
The first thing she does after getting home is come rub against her. She sleeps beside her at night and occasionally breaks into a cutesy voice.
Gradually, Fang gets used to it. Once she's better, bringing the girl back to the palace and indulging her should do no harm.
Later, after Fang Jinhen recovers, Xie Longxing notices that the woman's behavior toward her is getting stranger and stranger.
She's started touching, kissing, and hugging Xie just like before, whenever she feels like it.
Xie Longxing can't take it anymore and runs away.
She arrives in a small border town and lives happily, until one day, when the Empress makes a visit to Jiuhuai Mountain, Xie happens to run into her.
Xie Longxing tries to run, but gets pinned down.
Xie Longxing: "Sister, who are you?"
Fang Jinhen: "Don't you call me Master anymore?"
--?
Fang Jinhen was betrayed by the person she trusted most and fled into the mountains. She had no intention of ever trusting anyone again.
Until she opened her eyes through the haze and saw a young woman with red lips and pearly teeth kneeling before her, smiling as she called, "Master."
