(Time rewinds are used very sparingly throughout the story)
Lin Yun is an ordinary high school student who once had an unhappy relationship. After a freak accident, he unexpectedly gains the ability to rewind time. His relationship with a girl named Bai Ling develops quickly, but ultimately ends in regret. Later, he gets together with a girl named Guan Yunyun, but things still do not work out in the end. It is not that they are incompatible; they simply did not have enough time together.
