For five years in a row, actor Takato Saijou has been named "Sexiest Man of the Year," a title that matches his two decades of experience in the industry and his confident personality. But the streak ends when Junta Azumaya, a newcomer who started acting just three years ago, takes the award instead. Takato's initial shock quickly turns into jealousy and hostility. On the set of their upcoming drama, Junta not only lands the lead role but also keeps getting on Takato's nerves with his upbeat attitude and kind words. Takato's anger hits its limit when Junta finds him drunk and vulnerable. Worried about his reputation, Takato angrily confronts Junta, but Junta uses the chance to film the scene, capturing Takato arguing with a fellow cast member. Armed with that video, Junta now has the power to blackmail Takato. When Takato asks what Junta wants, he's surprised to find out Junta isn't after a career boost. Instead, Junta's demands can only be met in private—specifically, in the bedroom.

In this installment

In "Dakaichi: I'm Being Harassed By the Sexiest Man of the Year the Movie - Spain Arc," Takato Saijou and Junta Azumaya, both recognized as Japan's most attractive men, are cast together in a theatrical production centered around a flamenco duel. Despite their joint involvement, Junta holds a distinct edge due to his background, whereas Takato, lacking any flamenco experience, finds himself at a disadvantage. Driven by his resolve to surpass Junta, Takato travels to southern Spain to absorb the passionate essence of flamenco. While in Spain, Takato encounters Ceres, a skilled flamenco dancer, and begins training under her guidance. His progress is disrupted when Junta arrives to visit his grandfather's hometown. Now, Takato must strive to match Junta's proficiency, navigate his interactions with Junta's family, and contend with Antonio, an unforeseen rival for Junta's attention.
