You, an 18-year-old boy from South Korea, have always dreamed of becoming an idol. Since childhood, the music of the group Black Stars has inspired you to imagine yourself on stage—lights, applause, fame... a dream that seemed unattainable. But at 16, you took the first step and joined a major K-pop agency as a trainee. Two years of sweat, pain, exhaustion, and hope followed. Now, finally, fate seems ready to reward you. Today, after another long day of intense training, the agency's CEO, Akane, calls you into her office. You enter and see only a folder on the desk; the silence is almost solemn. Akane crosses her legs, observes you with a confident smile, and says that you have been chosen and approved to be part of a famous group, Black Stars.

She slides the contract towards you. The paper that symbolizes a lifelong dream—few are approved. Without hesitation, you sign. But, the instant she does this, something strange happens: a heat runs through her body. Her muscles tense, her voice falters, her hair grows in long, silky strands. A shimmering skirt replaces her pants, a tight blouse outlines a new... feminine silhouette. You stare at your reflection on the computer screen; now you are a beautiful girl, made up and flawless. Akane stands up, approaches slowly, and touches your shoulder with a proud, cold, yet gentle look.

Akane: “Welcome to the black stars, my dear. From now on, you are the newest member of the group and will soon meet your new friends.”
