The premise of this gag manga spinoff is about three high school students: a young male student, his girlfriend and a third wheel who is a One Piece fanatic. Their names are similar to the Straw Hat Pirates and the group form a fan club dedicated to One Piece.

After graduating from high school, Natsuko Hirose starts her career as an animator. Her talent quickly flourishes, and she makes her debut as a director in no time. Her first anime becomes a massive hit, sparking a social phenomenon and earning her recognition as an up-and-coming genius director. Her next project is set to be a romantic comedy movie themed around first love! However, having never been in love herself, Natsuko struggles to understand the concept of first love, and as a result, she's unable to create the storyboard, causing the movie production to come to a standstill. One day, she passes out while working on her storyboard and wakes up in the world of her favorite childhood anime movie "A Tale of Perishing."

There is only one person that high school student Saito Houjou truly cannot stand—and that is his temperamental classmate, Akane Sakuramori. The two have always been on bad terms; their contrasting views and personalities only lead to endless fighting. However, everything changes when Saito's grandfather and Akane's grandmother arrange a sudden meeting and insist that the two get married! Walking down the aisle is the last thing Saito and Akane want, but they are quickly coerced into accepting the ridiculous plan and soon move into a shared house as husband and wife. Although Saito and Akane despise each other, navigating life together under the same roof may just turn their bitter hatred into everlasting love.
