Pitch Perfect Love

One word from the right voice is all it takes to push former star voice actor Lim Sori over the edge. Ever since a past trauma left him with a secret, sound-triggered fetish, Sori has managed his urges in total isolation. That changes on a crowded train when Mi Inha speaks directly into his ear. Devastatingly handsome and deceptively gentle, Inha instantly sees through Sori's composure. Inha knows who Sori used to be, knows what his voice does to him, and has no intention of letting him walk away.
