Two people meet each other after missing the last train home, leading to a beautiful relationship over five years.
Yukiko Akaza attends a high school for blind. She has amblyopia, which causes her to recognize colors only vaguely and she can recognize large letters with a magnifying glass. When she walks outdoors, she always carries a white cane. Nevertheless, she has a bright personality. One day, Yukiko happens to meet delinquent boy Morio Kurokawa. At first, Yukiko doesn't like him, but she somehow gains an understanding of him. They become attracted to each other.
Hinako is the executive assistant to the CEO of Relation Gate, a startup company growing at breakneck speed. Apt to listen to his gut feelings, her boss bombards her day in and day out with tall orders he concocts on a whim. Life is far from chill for Hinako, who hasn't had a boyfriend in six years. She barely even has time to sit and think carefully about her future. Each long workday ends with the same toxic thought, "I find no meaning doing this!" as she clutches a beer and lets out a huge sigh.
