Ren Asakura is the quiet, gloomy student everyone ignores and he prefers it that way. After witnessing the brutal murder of his parents as a child and being forced to make an impossible choice, Ren closed off his heart and devoted himself to uncovering the truth behind their deaths. His only escape is the silence of books and the occasional flicker of peace in his otherwise grim world.

But everything shifts when a popular girl, Rika Hayami, gives him a sudden confession... only for it to be part of a cruel joke.

Ren sees through it immediately and calmy rejects her.

Yet that rejection sparks something unexpected. Instead of forgetting him, Hayami becomes increasingly intrigued by the boy who doesn't react like anyone else. Who is he really? Why does his loneliness feel so heavy?

As her curiosity turns to concern, and as their lives begin to intersect through accident and intent, Hayami is drawn into the mystery surrounding Asakura and the pain he keeps locked away.
