When their parents divorced at the age of 9, Jiang Mu and Jin Chao's lives entered a completely different double track from then on. She was in the south and he was in the north. Jiang Mu worked hard for schoolwork, and Jin Chao struggled for survival. Her world was so simple that there was only school and home in her life, and he had been in a state of limbo. She didn't know what else to worry about except for her abnormal performance in the exam and lack of sleep, while he had fallen into the world of the evil, walking on thin ice and besieged on all sides. Until they grow up to meet again, many years of concern on their way, and they embark on the road of recklessness for each other's dreams.
