The male protagonist Fang Yuan's parents died when he was young, and he lives with an adopted female civet cat "Ling Xue". On her 20th birthday, Ling Xue suddenly transformed into a beautiful woman and brought a five-pointed star pendant as a dowry, forcing Fang Yuan to marry her or else she would kill him. Fang Yuan was forced to agree, but his finger was bitten by Ling Xue, and blood dripped on the pendant. The pendant emits a ray of light and shines into Fang Yuan's brain, giving Fang Yuan the power "Beast Language".
