Koe ga Kikitai Kodaira-kun

Overview

"I really liked that voice—" On the day of the school entrance ceremony, Teppei Kodaira got absolutely charmed by the voice of Tsugumi Kuritani, who delivered a speech as the representative of the incoming freshman students. By complete coincidence, Teppei's seat in class was also right next to the owner of "that voice", Kuritani-san. But just when he thinks they'll gradually become closer... Kuritani-san sends him a message: "Teppei, it's embarrassing to let you hear my voice just for the sake of your reactions!" Kodaira-kun wants to hear her voice, and Kuritani-san doesn't want to be heard by him. A frustrating and "pure" romcom between these two begins!! (Source: Comipo, translated)
