Untitled Blue

Akari Ogihara (24), who has given up her dream of becoming a Japanese painter to support her family, one day rescues a man who has attempted suicide in the sea. The only thing she can learn about the man, whose age and name are unknown, is that he has a talent for Japanese painting. For reasons unclear, Akari lends him her name, "Akari Ogihara," and together they somehow begin selling Japanese paintings...?
