Office worker Koharu has one secret vice: erotic ASMR, the masturbation-support kind she plays through her earbuds every night. Then a flustered new hire, busty Azumi Rinka, greets her on the first day, and Koharu's body reacts to that voice like a trained reflex. What begins as mortifying mutual pining between coworkers unravels into late nights, roaming hands, and the discovery that the real thing beats any recording. Original title: 耳で恋した同僚 (Mimi de Koishita Douryou).
