Sore wa, Kimi ga Mita Ao Datta

A high school student named Momo lost her best friend, Sayo, in an unexpected accident. After eight years of separation, she meets Sayo's younger brother, Keichiro, at her funeral. Together, they revisit familiar spots from their past—like a secret base, a twilight-colored ferris wheel, and a candy shop they used to frequent. They search for the memories of a summer they were meant to share with Sayo. The story follows their journey through a bittersweet summer, filled with blue-hued graffiti and the emotions of those who have lost someone close. The work includes one epilogue and five additional bonus chapters.
