"You were the only one missing from the world."
About
In the spring of their senior year, four members of the art club nearing retirement couldn't forget a friend who had transferred away the previous summer. ──One day While tidying the clubroom, the four of them pulled out a framed painting tucked away in the storage room. It was a collaborative piece created last summer by the five of them, including the friend who transferred. On the canvas, five people were depicted laughing happily. However, from the day they saw that painting, strange things began to happen. Neither the teachers nor their classmates remembered the boy who was supposed to have transferred. It was as if he had never existed from the very beginning. Furthermore, the painting in the frame began to change little by little, with his figure and traces quietly vanishing. If he completely disappears from the painting── Will he vanish from their memories as well? Why was he the only one forgotten? Why are only the four of them able to remember? With the time remaining until their retirement, the four art club members begin to chase the mystery of their friend who is about to disappear from the world.
