Shogo became interested in painting at an early age thanks to his father, who owns an art gallery. Born into a family of artists, his older brother is a prodigy, and Shogo is often referred to as the "prodigy's younger brother." As a result, his love for painting begins to fade. Thinking a change of scenery would be for the best, Shogo's brother contacts a friend living on a small island and arranges for Shogo to move. There, he meets Ryosei, a boy with "hands blessed by god." Shocked by the overwhelming talent gap between them, Shogo makes a move, and Ryosei... This is a complicated yet pure romance brought to life by a paintbrush under the stars.
