It was revealed that the filming for the last episode of Rain's reality program 'Rain Effect' was temporarily suspended at one point.  People became curious about the reason behind this.

One rep of 'Rain Effect' said on January 23, "While filming the 'Natural Concert' portion of the last episode with the fans last week, the filming was temporarily suspended as Rain could not hold back the tears that gushed forth when he saw the surprise video prepared by the production team.  The relevant video was an interview with Rain's family and friends.  Rain especially burst into tears when he saw the interview video of his father; the production team were all surprised by this unexpected reaction."

In the last episode, which aired today, Rain personally prepared a concert event for his fans.  Rather than having a showy performance or dancing, Rain showed a different charm by performing a new, rearranged song with a live band.
