Mood Indigo (2019)

The story began when Kido Shirou reunites with his former classmate, Kijima Rio, at the funeral of their college teacher. In the past, Kijima, who was a student, showed his talent as a novelist and won a big prize. Kido was jealous of Kijima's talent, but reading Kijima's work made him fully aware that he had no talent, so he gave up writing a novel and became an editor in a adult novel publishing company. However, Kijima, who reunited with him, faced a slump as a novelist in a situation where he could not even pay his rent. So Kido asks Kijima to venture into writing adult novel.
