Taming the Mad Dog

Su Ruoshui transmigrates into the body of a vassal prince's daughter who is paralyzed in both legs. According to the plot, she'll find the male lead, Lu Jingchuan, on the road. He's posing as her younger brother, and she'll die protecting him, becoming a stepping stone on his path to success.

Her younger brother went missing at the age of five and has now been gone for eleven years. With a face that looks even more like their family than her real brother's, Lu Jingchuan suppresses his desires and ambitions. After lying low for three years, he inherits his father's title, becomes the youngest vassal prince, and ultimately claims the throne.

As Lu Jingchuan's power grows, so does his desire for Su Ruoshui.

The moon hangs high in the sky. He wants it all to himself.

A gloomy, vicious dog vs. a beauty like the bright moon

Romance-focused, not a strong female lead, in fact, she's even fragile (emphasis added). A gloomy atmosphere, a bad male lead, and a female lead who attracts many admirers. Short story, older woman and younger man.

Theme: Running away may be shameful, but it works
