This is a world where plants can grow from human bodies. But due to a certain "incident", plants no longer grow from the body of Hana, the protagonist of this story. After her class had a change in seating arrangement, the boy who moved next to her confessed to her and slowly, her colourless days begin to change. This is a beautiful love story that paints the subtleties of a pubescent girl's delicate heart and the vibrant colors of plants.
