After Guest's passing, the relationship between three people begins to change drastically.
Toka Shizuki, Nemuri Yoizaki, Kuro Sakakiya, and Guest were all second-year high school students in the same class.
One day, Guest died suddenly in a traffic accident.
Only the seat that was occupied until yesterday remains empty, with flowers placed on the desk.
However, just because Guest is gone does not mean time stops for those left behind.
Toka, who lost her lover.
Nemuri, who lost her first love forever.
And Kuro, for whom the obstacle to obtaining Toka has disappeared due to that death.
With Guest's death as the turning point, the relationship between the three, which had barely been maintained until then, begins to quietly crumble.
