Seven moments that high school graduate Seiichi Yukimura recalled on his graduation day.
They are seven moments of memories and seven moments of youth:
Seiichi Yukimura, who is in the third grade of junior high school, accidentally meets a girl in Kirihara's class who doesn't like to talk and is too quiet: Wakamizu Han.
His country is third and her country is second.
The library and the station are most of the backgrounds.
Their meeting and communication can only be described as two lonely people warming each other up.
In the end, this period of youth was fruitless because Ruo Shuihan was introverted and did not like to communicate with others.
"Graduation day is both the end and the starting point. The reason why Yukimura thinks of her is so that he can forget her at this end.
But at the seventh moment, he found that he could not forget her at all. This green and sad feeling was truly rooted in his life. As written in Chapter 7, "That's wrong. Even when the world loses its memory, he will still think of her habitually. This is an indispensable part of his life. It's just that they met too early, so early that they don't understand what love is. By the time they understand, it's already too late."
The full text is structured in the form of memories, combining the day of the graduation ceremony with Yukimura's constant memories.
