Two coworkers, Yuuna Inukami and Yuuto Sarushima, constantly bicker over work ideas and trivial matters, but their constant fighting masks a deeper attraction. After a drunken night they can’t fully remember, they wake up knowing they had passionate sex, which becomes the catalyst for their relationship to evolve beyond rivalry. They begin dating while maintaining their combative dynamic at work, but their sexual connection becomes increasingly intense and consuming. As their relationship progresses, they engage in competitive “showdowns” both in and out of the bedroom, with their playful rivalry transforming into genuine intimacy, culminating in them settling their disputes through games and physical competition while their feelings for each other deepen despite their constant bickering.
