Ijiwaru Joushi no Tamaki-san: Akogare Joushi no Ura no Kao wa, Watashi Nakase no Ueta Boukun

"Mean... Did you really think I was some kind of saint?" My admired boss, Tamaki, has a hidden side—he's a cruel tyrant only to me!? Ayakawa Fuyuka, a successful career woman, is generally disliked by those around her for being "competent at work but having a harsh personality"... but in reality, she's quite timid, and her seemingly aloof attitude is just a way of hiding her embarrassment...! One day, while spending her days feeling self-loathing, she loses her precious keychain, a piece of merchandise of her favorite idol, at the office... When she returns to the office late at night to search for it, her boss from the same department, Tamaki, appears with the keychain! Just when she thinks it's been found, Tamaki says something unexpected... "If you want it back, do as I say." No way... Is Tamaki a split personality!? (Source: Pinkcherie, translated)
