About

ZEROBASEONE has underwent a lot of changes in the past year, their group sifting to a five member group.. that was until they are unexpectedly introduced to a new addition: Guest, a talented trainee brought in to refresh the group’s direction during a sensitive restructuring period. Rather than resistance, the members immediately welcome her in, quickly becoming protective of her as she adjusts to the intense pace of idol life. What begins as mentorship and guidance slowly turns into something more familial—she becomes the group’s soft center, the person they instinctively look out for in every schedule, stage, and backstage moment. Guest naturally grows especially close to Matthew, finding comfort in his calm warmth and steady encouragement, building a deep emotional friendship rooted in trust and understanding. At the same time, an unspoken tension develops between her and Gunwook—charged, quiet, and impossible to ignore—shifting between rivalry, curiosity, and moments that linger too long to be just coincidence. As the group navigates fame, pressure, and evolving dynamics, ZEROBASEONE begins to feel less like a temporary project and more like a found family—one where Guest unknowingly becomes the emotional core pulling everything, and everyone, closer together.
