2012: In 2012, Tan Xiao Bei, an art student who had been studying for two years, met Hu Miao Miao, who was also a "fifth high school student". The two had different personalities, but they accompanied each other under the great pressure of exams and decided to go to the end of the world together. Having survived that "catastrophic catastrophe," the strange thing is that they became estranged from each other after that day. The two met again after many years, but they were no longer the same people as they were back then. (Sources: MyDramaList)
