START-307 — By Day, The New Female Announcer Koi Is A Pure And Innocent Girl, But By Night, She Helps Me Practice My Voice While I'm Working Overtime. She Whispers Extremely Vulgar And Pure Dirty Talk In My Ear, And Comforts Me With Her Gentle, Embracing Finger Technique And Nipple Licking. She's My Divine Classmate, Nagisa Koi.

Nagisa is an elite among elites, the only new graduate to be appointed as an announcer at SODTV in 2024. He is humble and pacifist, and has a good personality. No matter how hard we commoners who joined us at the same time, we can't compete with Nagisa. But Nagisa has a secret that he keeps hidden within the company. A secret that only Nagisa and I know. To be honest, we are dating.
