D-Don't Pull Them Down, Don't Pull My Swim Trunks Down.

Synopsis

After wrapping a commercial shoot in Hawaii, Takato relaxes on the beach to spend the rest of his stay resting. Just then he runs into Azumaya, who came to Hawaii for a magazine shoot. Azumaya is delighted to get a beach date where no one will recognize them—but they happen to bump into Ayaki and Narimiya, and the four of them end up together.
