Gu Yingyou is an aloof beauty, a leading professor, and a woman who despises “improper drugs” above all else. To rid the world of these harmful substances, she tests them on herself... No, she devotes herself to research. But an experimental mishap sends her rationality spiraling out of control, and at that very moment she runs into her arranged-marriage match, Ying Chen, who’s known as a playboy.
After one chaotic night, Ying Chen decides to take responsibility. After they marry, Gu Yingyou discovers that he’s nothing like the playboy people described. But just as she starts falling for him, she learns that Ying Chen may be keeping someone on the side?
What she doesn’t know is that the adorable, clingy sweetheart Ying Chen talks about is just a ragdoll cat his friend gave him.
