Ryousuke Hazuki is a young man whose heart has been captured, leading him to stop by the local flower shop every day just to catch a glimpse of Rokka Shimao, the beautiful owner. Hoping to get closer to her, he decides to take a part-time job at the shop, but before he can make his move, he encounters a major obstacle: a ghost lives in her apartment, claiming to be Rokka's deceased husband. Atsushi Shimao has quietly watched over his widowed wife since his death three years ago. However, Hazuki is the first person to ever notice him, and the two quickly find themselves at odds: the jealous Shimao attempts to thwart the suitor's advances and possess his body, while Hazuki simply wants the ghost to pass on for good, allowing Rokka to move on from the past and him to be with the one he loves. As both men refuse to let go of their desires, an unusual relationship forms between a troubled woman, an unrelenting ghost, and a stubborn man in love.
