Yoshiko plans a vacation with fiance Kitaoka, when suddenly he is unable to attend. She goes by herself and winds up double booked with Oda Ryuunosuke.

Yoshiko Suematsu plans a one week vacation to a cottage in Miyazaki prefecture with her boyfriend, Shuichi Kitaoka, who is the head of the Development Department at her company. She's determined to settle the issue of marriage with him there, but Shuichi suddenly has an urgent matter at work and cannot leave with her. Yoshiko sets out for the cottage by herself and waits for him there. Due to a mistake in booking, Yoshiko ends up having to stay there with science fiction novelist Ryunosuke Oda. Both are very prideful, and say exactly what they want to each other. And slowly, they begin to lie to each other. Yoshiko refers to Shuichi as her husband, and Ryunosuke brags about how many novels he's sold. Just what will happen with these three?
