Xu Tang had the same dream for several days in a row, in which her boyfriend Zhou Yanhan was attacked by the transfer student Shen Yuan and eventually abandoned her at the wedding. Until Shen Yuan actually appeared in reality, Zhou Yanhan was always cold and distant, completely opposite to that in the dream. Xu Tang gradually realized that it was not a dream, but a memory from the previous life - Zhou Yanhan had left to "save" Shen Yuan, and she had left alone. Now that he was reborn, Zhou Yanhan tried his best to make amends, but Xu Tang discovered that some cracks could not be healed even if he was reborn. She finally chose to leave, and fate seemed to have already written their respective endings.
