Five years ago, Min Hui became entangled in a complicated love story with Xin Qi. To comfort his dying childhood friend, she pretended to be her—and unintentionally fell in love with him. But when Min Hui discovered Xin Qi suffered from a serious heart condition, the truth became harder to reveal. Each attempt to come clean was met with disbelief or illness, and when Xin Qi finally uncovered her secret, he felt betrayed and walked away.

Now, years later, fate brings them face-to-face at a business event. Min Hui is a talented R&D assistant, and Xin Qi is the CEO of a leading investment firm. Still carrying the pain of the past, Xin Qi channels his unresolved emotions into cold resentment. But everything changes when he discovers that Min Hui has a young son—his son—who also suffers from the same heart condition.

As they navigate co-parenting, lingering emotions, and unexpected living arrangements, Min Hui, Xin Qi, and their spirited little boy find themselves in a heartwarming journey full of humor, healing, and second chances. Can love grow again from the ashes of the past? And can they finally become the family they were meant to be?
