Hoshino Arata (Okada Masaki) is a apathetic university student who feels that hard work alone is useless and that the future cannot be changed. But one day, he obtains a mobile phone journal in which the future is written. In order to change his own terrible future which is found inside, he gets caught up in a game of survival with people who have this same journal of the future including Furusaki Yuno (Goriki Ayame) who has a crush on Arata and always turns up wherever he goes. At first, he simply runs away, but grows up through encounters and separations from friends. He realises the “true identity” of the journal and tries to win to stay in the game. He decides to live according to his own will, and gets the message that there is hope and there is a tomorrow.
