Song Yuxuan's mother and father eloped to Jiangcheng. Her father died of lung cancer not long after Song Yuxuan was born. Her mother died in a car accident on the way to send Song Yuxuan to take the college entrance examination. She was taken back to the Song family by her mother's family and cut off contact with everyone in the past; Being involved in the interest disputes of the Song family for no reason tempered Song Yuxuan into a numb person. Later, Gu Liu found her, solved the previous misunderstanding, rescued her from the dispute, and cured Song Yuxuan's illness. The two fell in love.
——"My name is Song Yuxuan, superfluous Yu."
"My name is Gu Liu, stay here."
In fact, Yu also means remaining. I mean, you are not redundant, but a kind of beautiful memory left behind.
