The narrative centers on Eiji Kirisame, a seasoned 40-year-old detective who encounters the most baffling witness of his career during a criminal investigation. That witness is Tsugumi Kuchinashi, a quiet high school student present at the crime scene.

Tsugumi communicates her testimony entirely through crude doodles drawn inside her sketchbook. While others dismiss her drawings as useless scribbles, Eiji takes every single page seriously to piece together the truth behind the crime. However, the investigation takes a shocking personal turn when Eiji flips to the final page of her sketchbook only to read a sudden proposal: “Will you marry me?!”
