Overview:Io is an art student who has a habit of keeping a dream diary. After losing her lemon-colored paint somewhere, she became close to Miyama-senpai, and he invited her to work part-time at a furniture store. One day, a gigantic man she met at her delivery address confessed that he was a classmate in elementary school, but the moment she heard that name, a shudder pierced through Io's whole body. As the world suddenly begins to unravel, dreams and dreams resonate with each other, and an unexpected truth is brought to the memories of first love colored in pale lemon.
