Su Wan is a Cinderella who lives under someone else's roof. She lives a cautious life in the Lu family, but she hides her desire to pretend to be a pig and eat the tiger. Unexpectedly uncovered the secret of Lu Yu, the young master of the Lu family who is "unacquainted with worldly affairs" - he seems to be innocent, but in fact he speaks dirty words and makes people's ears burn.
Psychologically twisted suitors stalked her, rivals in school stumbling upon her, and Lu family relatives made things difficult for her like a tidal wave. Su Wan put away her weakness and fought back with wisdom, but found that Lu Yu was always helping her in the dark, and even whispered in her ear: "Wanwan, are you tired of pretending to be good? I'll play with you."
Just when Su Wan thought he could control everything, Lu Yu's "ignorance of the world" suddenly collapsed, revealing his true face of overwhelming possessiveness. He cornered her: "Wanwan, you can't escape." And when he missed her out of pride, the prelude to the crematorium of chasing his wife had just begun.
