Takamiya-san ni wa Himitsu ga Aru

Noboru Hirata, a white-collar salesman, spends his days working under the eye of Misaki Takamiya, the president's secretary who's admired from afar by co-workers both male and female. One day, Noboru's co-worker plays a prank on him and downloads a gay hookup app onto his phone. Out of curiosity, he decides to give the app a shot, and to his great surprise, finds a profile with photos that eerily match those of his internet crush, "Misaki." With surprise and anticipation, Noboru starts to wonder... What if his beloved "Misaki" is a man? Noboru matched with Misaki. The conversation was lively and the distance between the two grew closer, and they finally decided to meet at a hotel. However it turns out the person who came to the hotel is, Misaki Takamiya, his workplace's Madonna!?
