The Future Diary is a love diary of events that will happen in the future. Two people who have never met before are cast to live out a romantic storyline by following a diary that is handed to them. Their semi-fictional exchange, based on the casts’ own words, takes them through an experience that could ultimately influence how they view one another. Will the adventure lead to real romance? A reboot of the legendary romance reality series that made 20 years ago starts from December 14, 2021.
