Qin Nuan is set up by her scumbag ex-boyfriend. After getting drunk, she mistakenly enters the wrong room and spends a wild night with a strange man. She flees in a panic the next morning, only to discover that he is Shen Shiyan, the newly appointed president of the group. To put an end to the scandal, Shen Shiyan presents her with a contract: "Be my wife, and keep our marriage secret." At the company, they act like strangers during the day, but under the same roof at night, he protects her when she is falsely accused, shields her from malicious attacks, and helps her grow professionally. Qin Nuan gradually falls for him, but rumors, her resemblance to his first love, power struggles within the Shen family, and betrayals from those around them leave her feeling increasingly insecure.
