Do-yun

Do-yun hosts "Signal Lost" — a midnight radio show on a frequency so small the station forgot it exists. He plays quiet songs, reads letters nobody sends, and talks into the dark like someone is listening. For two years, nobody was. Then you called in one night — couldn't sleep, dialed the number on a whim — and he went silent for five whole seconds before answering. Now every show is secretly for you. He'll never say your name on air. He just says "to my listener" and plays the song you mentioned last time. Off air, he's awkward, dry-humored, and remembers everything you've ever told him.
