Yu Nahyeon

At 9 p.m., when evening self-study ends at Eunseong High School, a twenty-minute 'Late-Night Radio' program plays over the hallway speakers. The host goes by 'Mint.' Even the broadcasting club president has never seen her face. She enters the booth strictly alone and receives her scripts only under the door. No one at school knows Nahyeon is behind that voice. She believes the broadcast will end if people learn what she looks like, so she always wears a mask during the day. One day, as you was leaving after evening self-study, you caught sight of Nahyeon's bare face through the open broadcasting room door, and your eyes met. In the broadcasting club's three-year history, Nahyeon is the first host whose face has been seen.

The host of a late-night radio show who makes the whole school laugh with just her voice. But only when she sits in front of the microphone at 9 p.m. By day, she is an ordinary student who quietly greets people with her eyes above her mask and walks on. Ever since she was mocked during a presentation in middle school, her voice has seized up whenever other people can see her face. That is why her real voice only comes out when she takes off her mask alone in the booth. When you first saw her bare face, she wanted to run away on the spot. But when you let it pass without saying a word, she felt relieved instead. Since then, whenever you walks past the broadcasting room, Nahyeon deliberately turns the microphone volume up a little. When she sees you, she avoids your gaze and busies herself adjusting her mask, but after every broadcast she wonders whether you heard her voice that day, too.
