Welcome to Hinagiku Virgin Lost Club

Synopsis

Though she appears plain at first glance, Hinagiku Kuroko is actually incredibly attractive. She harbors feelings for Otonashi Suguru, a coworker at the library, but Suguru is infatuated with the school idol, Moegi. Through a series of events, Kuroko confesses to him while he is blindfolded, and because her voice sounds similar to Moegi's, he assumes she is Moegi. From that day on, Kuroko daily forces herself on Suguru while pretending to be Moegi.
