1004 (Cheonsa) is a contemporary story set behind the scenes of K-pop. Angel Willson, an Australian-Korean PR manager living in Manhattan, is raising a child she adopted after losing a close friend. When her job brings her back into the K-pop world, she is assigned to work with BYGONE—a global group inspired by the kind of bonds and leadership fans love in groups like Stray Kids. As Angel grows closer to BYGONE’s British-based leader, Alex, strict dating bans, intense fandom pressure, and her role as a single mother collide. Her son Sam already sees the idol as family—something that could destroy everything if it’s discovered. This book explores the reality behind K-pop fame, the pressure idols face when it comes to love and family, and the impossible choices women make when career, motherhood, and desire overlap. I added a small Korean glossary at the end of the book for anyone who’s learning their first Korean words through K-pop.
