The Future Diary is a love diary that chronicles future happenings. Two persons who have never met before are cast in a romance plot based on a diary given to them. Their semi-fictional discussion, based on the actors' own words, puts them through an experience that may alter how they perceive one another in the future. Will the adventure lead to true love? The renowned romance reality series, which debuted 20 years ago, will be rebooted on December 14, 2021.
