Cha Le, because of family reasons, she didn't like to laugh since she was a child, so she had almost no friends. The only brother who understood her heart, Cha Yixun, also died in a car accident.
When she was ten years old, Chale's parents went to an orphanage to adopt a child. From then on, her closed heart became even more difficult to open. But who knew that Zha Yixuan would slowly approach her heart.
Challen was worried that Cha Le and Cha Yixuan would outgrow the relationship between brothers and sisters, so he sent Cha Le to go abroad. However, Zha Yixuan got into a car accident on the way to the airport, and recovered his memories before he was seven years old and forgot the time he spent with Cha Le.
When we met again seven years later, Chale was already a seventeen-year-old girl, but she became mute and never spoke a word again.
And Cha Yixuan unexpectedly became the popular singer Gu You. The filming of a TV series made them meet again. Will they join hands with him or stop there?
