Many years ago, the girl was abducted and sold to the mountains by human traffickers, where her parents named her Mean Girl. The girl was beaten and scolded by her adoptive parents until she went to work in the fields one day and was awakened by a boy during her lunch break. He took her out of the mountains and changed her name to Shengsheng. He hoped that the girl would always be kind and pure. After the city stabilized, he took Shengsheng to find his biological parents but learned that he had been sold to human traffickers. "Shen Yunzhou, there is still a big mountain in front of the mountain", so the two began to depend on each other. While he was healing Sheng Sheng, he was also being healed by Sheng Sheng. The two developed feelings while getting along.
