English titled Operation Love, was a TV series in spring 2007.
To briefly summarize, this 11-episod series is a series of time travels that a fairy offered Ken, the protagonist, to go back in time to fix some mistakes he had made in order to pursue the girl who he loves, who is now the bride of somebody else. The fairy appears on the banquet night, pitied Ken who regrets every single thing he did in his life and gives him the power go back.
One good thing about Japanese TV series is that it is very short per season. This in particular reminds us to live without regrets, and to be brave to face the difficulties in life, especially in our relationships, not only with lovers, but also with family and friends. MEANINGFUL! Go get it!!
Here's a fan-made MV of the theme song: 明日晴れるかな by 桑田佳祐. Sorry this is the best I can find, no English subtitles, just Chinese...
