Dou Xiaowei accidentally added "Yin Yang Q" (the same QQ as her own account) and met Lang Yuwu, who was said to have died in an accident. In order to win back his girlfriend Li Mengmeng, Xiao Nanxing used hackers to create a supernatural illusion and offered Dou Xiaowei as a "sacrifice" to Lang Yuwu to resolve his own crisis. Dou Xiaowei was heartbroken after learning the truth, but fell in love with each other while getting along with Lang Yuwu. At the same time, the truth about Lang Yuwu's accidental death due to Liu Yanchao's jealousy and Wang Siyu's misunderstanding was revealed. In the end, Lang Yuwu lost his soul to protect everyone. Many years later, Dou Xiaowei stayed in school to wait, and unexpectedly received a QQ reply from Lang Yuwu.
