Yan Qing is a successful businesswoman and the heiress of the Yan family, having co-founded the jewelry company Yuerong at a young age. Despite her professional achievements, her love life has been plagued by bad luck, with every romantic prospect ending in betrayal or abandonment. Her father, Yan Nan Shuo, exerts significant control over her personal life, freezing her financial assets and forcing her into blind dates to ensure she marries within acceptable social circles. Yan Qing’s best friend, Zhan Yunduan, attempts to set her up with a gentle college student named Zhan Yan Chen, whom she describes as a sweet and harmless companion. However, on the night of her birthday, Yan Qing becomes intoxicated and mistakenly identifies Zhan Yan Chen as the notorious Crown Prince of the Capital Circle, a figure rumored to be a ruthless and dangerous man. The misunderstanding leads to an impulsive night together, after which Yan Qing discovers the truth: Zhan Yan Chen is indeed the Crown Prince, the powerful heir to the Zhan Corporation empire, and he is four years her senior.
Facing pressure from her father to enter an arranged marriage, Yan Qing proposes a contractual union to Zhan Yan Chen, hoping to secure her independence while providing him with a wife. To her surprise, he eagerly accepts, and the two obtain their marriage certificate within hours. Zhan Yan Chen continues to pose as a student, hiding his true identity from Yan Qing because he knows she has a strong aversion to wealthy men and family dynasties. He moves into her penthouse, carefully maintaining the facade of a dependent husband while secretly managing his vast empire. Their relationship evolves from a transactional arrangement into a deep emotional bond, characterized by Zhan Yan Chen’s protective nature and Yan Qing’s gradual realization of his true capabilities and devotion.
The narrative introduces several conflicts, including Yan Qing’s past trauma involving a man named Xia Jin, who falsely claimed to be her savior five years prior. It is revealed that Zhan Yan Chen was the one who actually rescued her during a fire, an act he kept secret. As Yan Qing’s father uncovers the truth about her benefactor, the tension between the families and the hidden identities creates a complex web of secrets. Meanwhile, Su Qianqian, a childhood acquaintance of Zhan Yan Chen who has harbored unrequited feelings for him for years, becomes a rival, attempting to undermine Yan Qing’s position. The story also explores the lives of Yan Qing’s other close friends, particularly Rong Yan, a top lawyer who struggles with her own unrequited love for Fu Zhan Yu, a man entangled in family politics.
As the plot progresses, Zhan Yan Chen’s dual life becomes increasingly difficult to sustain. He balances his role as the feared Crown Prince in the business world with his persona as a devoted, albeit slightly clingy, husband. Key turning points include Yan Qing discovering Zhan Yan Chen’s true identity through his actions and the growing affection between them, which challenges her initial reservations about marriage. The story culminates in a series of confrontations where Zhan Yan Chen protects Yan Qing from external threats, including corporate sabotage and personal vendettas, while Yan Qing learns to trust him completely. The narrative focuses on the transition from a marriage of convenience to a partnership built on mutual respect, love, and the unraveling of long-held secrets, ultimately leading to the acceptance of their union by both families.
