Rewind 1999

A pair of former friends (and business enemies) who broke up due to a major accident were simultaneously involved in a mysterious "time fold" in 2024, and were forced to share the ability to intermittently go back to 1999, the starting point of their friendship. They must travel between the intrigues of modern business wars and the tenderness of the past. While solving the mystery of trauma, they must prevent a greater crisis that is about to happen in the present.
