Twenty-three years ago, Shen Yue, the cherished daughter of the Shen family, was switched at birth and abandoned on the streets. Twenty-three years later, starving and freezing, she happens to meet Shen Chongyue, and the crescent-moon birthmark on her forehead brings back his memories.

As the truth behind the baby swap comes to light and father and daughter reunite, can the emotional void left by twenty-three years of lost family bonds be filled?
