The story primarily revolves around the situations that arise when a pair of opposite sexes go on a date on an uninhabited island. The anime features 22 characters representing different professions and unique personalities. Each personality can spark different kinds of interactions—some might be infuriating, while others could become heartwarming memories that make you smile. Although the circumstances vary from good to bad, they are all things that could happen around you. And because all these events take place on this island, it is aptly named "Doo Island."
