At eighteen, Seong Eunji deals with some tough things in her life. The only thing that keeps her from slipping completely into the dark is K-pop. With blocking out the noise in her life, one group becomes her safe place. Their songs speak the words she never learned how to say. Their laughter fills the silence of her room. Her bias feels like proof that hope can exist-even from far away. Through their music, she survives nights she never thought she would. But idols are human, too. When tragedy strikes and she can't save the one who saved her, everything shatters. The group disbands under the weight of loss, scandals, and grief. The songs that once carried her through her hardest days become too painful to listen to, and without realizing it, she loses a part of herself along the way. Ten years later. At twenty-eight, she is no longer the girl who hid in her headphones. She's a journalist, chasing stories. On the surface, she's composed, articulate, successful-but beneath it all, the echoes of those songs still live inside her. When her work begins to pull her back into the world of K-pop-uncovering hidden truths, buried grief, and the cost of fame-she's forced to confront the night everything changed. What really happened to her bias. What it meant to lose him. And whether healing means letting go... or finally telling the story that was never told.
