Kimi no Koe ga Sukisugiru

Mika, a college student with a deep voice obsession, meets her handsome boss, Misaizu, at her part-time job. Hearing her idol's voice up close and personal, her rosy days begin. Misaizu develops an interest in Mika, who is obsessed with the things she loves, but his "face" is no match for Mika, who is only interested in 2D and can't tell the difference between handsome men in 3D. Through one twist and turn, the two become otaku buddies...!? A love comedy about a girl who's not used to love and a guy (who should be popular) whose love life isn't going the way he wants!
