The future, romance, and everything else remain "undecided," yet the remaining days of high school seem poised to pass in the blink of an eye. Mikako Ichimura is 17 years old. Midorikawa is the strange boy who now sits beside her following a seating change, oddly favoring red pencils. At first, Mikako paid it little mind, but upon discovering they share a love for the same band, their relationship begins to shift bit by bit... The day-to-day life of a 17-year-old girl, woven together in a soft literary style.
