When Yan Jiexi returned to the country and was being pestered relentlessly, she appeared and helped him. The name that slipped from his lips became the bond between them at their first meeting. After Sunny abandoned him, Yan Jiexi shut his heart away, never expecting to meet another Sunny in his own home.
Xuanze Qing grew up with her single mother and never knew who her father was. When she was eleven, her mother passed away too, so she was taken in by her uncle's family. They loved her like their own daughter, and she grew up without a care in the world. But everything that happened in her childhood had already shaped her character. She grew up relying on no one, and no matter who was gone, she could still live happily.
At seventeen, Xuanze Qing was already a somewhat well-known writer. That was also the year she met a strikingly beautiful boy with a story of his own.
Yan Jiexi and Xuanze Qing interacted as cousins. They acted together and went to school together. But as they grew closer, long-buried events slowly came to light.
Everyone always says that Xuanze Qing is a true sunny day, able to bring happiness to those around her. But in her heart, she has only one wish: that the people around her will be happy, even if she has to trade away her own happiness to make it happen.
