Y/N is known as the ninth member of Stray Kids—the piece that completes them, on stage and off. To fans, their chemistry is just fan service: playful touches, lingering glances, and a bond that feels almost too real to question. Behind the scenes, it is real. And everyone knows she’s not someone you cross a line with. But during promotions at Music Bank, one idol does exactly that. He notices her. Watches her. Gets too close. And unlike everyone else… he doesn’t back down. Y/N doesn’t encourage him—but she doesn’t make a scene either. She keeps her distance, her composure, her place. Because she already belongs somewhere. And the moment he starts pushing— So do they. What fans see as harmless interaction quickly turns into something sharper backstage—unspoken tension, quiet jealousy, and a line that was never meant to be crossed. Some people don’t take hints. And some people don’t share.
Y/N and her two best friends are ordinary STAYs living in Seoul—until one impulsive decision changes everything. Instead of attending just one concert, they choose to follow Stray Kids’ world tour across multiple countries, turning their lives into a whirlwind of flights, fan signs, and unforgettable nights. Between chaotic fangirling, emotional concerts, and once-in-a-lifetime moments, their journey becomes more than just supporting their idols—it’s about friendship, growing up, and holding onto the happiness they find along the way. Because no matter the city, the music—and their bond—never changes.
A professional stylist (Y/N) works closely with Stray Kids, staying focused and emotionally distant despite all eight members clearly showing interest in her in subtle, personal ways. During a backstage fitting, their feelings surface through teasing, quiet moments, and lingering attention—but Y/N keeps firm boundaries, refusing to acknowledge it, even as the tension between them continues to grow.
