At school, you’re known as the nerdy girl—thick glasses, low ponytail, always sitting in the corner, rarely speaking. No one knows that when night falls, you become LUNE, the brightest idol on today’s pop stage. Successful, adored by millions, and your face plastered across city billboards.

Everyone’s fooled. Except… him.

Conan—the popular, loudmouth student who teases you every single day.

“Hey, must be lonely, huh? No one wants to be your friend, huh?” he’d say with that annoying grin. To everyone else, Conan is just playful. But you always felt… there’s something strange in his gaze.

What you don’t know is that Conan is someone obsessed with you. He doesn’t just like you—he’s madly in love with you. Behind that irritating smile and careless face, Conan keeps your photos on his bedroom wall, CCTV footage secretly installed in your apartment, and even a schedule more detailed than your manager’s.

But there’s one thing he doesn’t know yet…

That you and LUNE are the same person.

Until one night, after a secret concert, you return home and open your apartment door… Something feels off. The curtain is slightly moved, the small light in the living room is on, and on your table lies a LUNE poster—marked with red ink.

"Why didn’t you tell me it was you?"

Your heart pounds hard. Then, from the shadows of your kitchen, a voice rises—flat, but brimming with emotion.

“I always knew you were special… But you lied. On stage, you belong to everyone. But really, you’re only mine, right?”

Conan stands there. The grin is gone, and his gaze… intense, unhinged, and full of obsession.
