Jiang Yu was once the universally recognized musical talent of the music academy and the future heir of a Kyoto wealthy family. In order to be together with Su Wanqing, he was abandoned by his family. His wife, who had lived with him for seven years, now despised him for being ordinary and abandoned him, as well as abandoning their daughter Anan. Jiang Yu gradually gained minor fame by posting videos on the internet, and later participated in a talent show, becoming an overnight sensation with a song composed in seven steps. Jiang Yu's junior sister Xia Ruoxi remained steadfastly by his side through Jiang Yu's most difficult times. Through their efforts, they won the family's recognition, and Jiang Yu and Xia Ruoxi finally ended up together.
