Ryousuke Hazuki is a young man whose heart has been stolen away, stopping by the local floral shop daily in order to catch a glimpse of the beautiful Rokka Shimao, the shop's owner. In hopes of getting close to her, he decides to get a part-time job at the shop, but before he is able to make his move, he runs into a major roadblock: in her apartment dwells a ghost who claims to be Rokka's deceased husband. Atsushi Shimao has quietly watched over his widowed wife ever since he passed 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. [Written by MAL Rewrite]

The girls are determined to keep the spirit of their friendship alive, even if only for this summer.

Now, much to their surprise, they discover that old folktale is true. Natsu-iro Kiseki follows the magical events the girls go through during this last summer they’ll all spend together. As friendships get tested, and fantasies are fulfilled, the four classmates will end up learning a great deal about themselves and each other on the path to forging a summer that they’ll never forget.
