Is there a song that will remind you of me?
Is the song coming from the radio the theme song of our love?
In past and present lives, we use songs to tell our stories??

Seeing the time before 2004: It's all my imagination... Don't take it too seriously! Of course, if there are related events mentioned in the plot, such as investment failure, these will also be used.
See 2004: basically the year of rebirth! (So it seems that they got to know each other early.)
Seeing the time point after 2004: The added [Previous Life] is basically the content in the TV series (of course some of it is added by myself). If you have watched it, you can skip it or reflect on it. If you haven't watched the TV series, you can find out more. What is not mentioned is the plot development after rebirth.
