Maris, the daughter of the well-respected Mackenzie family, has one ideal man, and he's a horse! A famous horse named Soul Pleasure. "His tight body, his intelligent black eyes... There's no man in the world as spectacular as this horse!" she says. But one day, she happens to overhear a plot to murder Soul Pleasure, and then she's struck by the criminal, losing consciousness. The next day, she finds herself in bed with a half-naked man—one so handsome it's as if Soul Pleasure himself had turned into a human being!
