When she was six years old, her parents broke up and a broken marriage completely separated a pair of sisters who depended on each other for life. Chu Lan was forced to change her name to Chen Yutu and follow her mother away from the painful home. However, her sister Chu Hu, in order to protect her mother from being hurt by her father, reluctantly chose to stay in that suffocating place. The words "live a good life" became the last agreement between the two when they were young. From then on, they grew up alone in their own worlds separated by an insurmountable gap.
Many years later, Chen Yutuo became the most rebellious and indifferent girl in the fourth class of high school. She smokes, skips classes, falls asleep in class, and has an indifferent attitude towards everything, hiding all her vulnerability under a cold appearance.
Close relatives who were forced to separate in the past reunited in the most unexpected way. One is full of edges and corners, hiding childhood scars; the other is silent and strong, carrying years of worries. The regrets, grievances, longings and pain of the past are intertwined, binding the two together again.
Concept: A pair of sisters who were separated when they were young reunited many years later. From painful alienation to falling in love again, they redeemed each other.
