A childhood betrothal brings Leng Xiwei, a woman from an ordinary family, into a marriage with Lu Jingbo, heir to the wealthy Lu family.
But Lu Jingbo still cannot let go of his first love, who has spent years abroad.
Treating their marriage as a business deal, Lu Jingbo uses a clever trick to get Leng Xiwei to sign a divorce agreement.
He thinks it is purely a transaction for mutual benefit, but as they spend time together, he is gradually drawn to Leng Xiwei’s resilience and independence, and begins to show her small acts of care.
Leng Xiwei’s frozen heart slowly begins to thaw, but just as their feelings grow stronger, his first love returns from abroad.
Determined to win him back, she secretly schemes to drive a wedge between them, creating misunderstandings that make Lu Jingbo treat Leng Xiwei harshly. Leng Xiwei mistakenly believes that Lu Jingbo still has feelings for his first love, and, heartbroken, resolves to leave him.
Only after Leng Xiwei leaves does Lu Jingbo realize he has fallen deeply in love with her. He sets out to win his wife back.
