#1 Eternal Hour starts off as a slice-of-life game about the daily life of average-yet-interesting boy named Yasu Fujimoto. Yasu had a pretty peaceful youth living with his aunt, but all is slowly changing as Yasu and his friends are closing in on the end of their high school life. Yasu fears that he is running out of time, and feels a suffocating pressure made by his own indecision and lack of achievements so far.
