Exam week was already hell, but your twin brother made it worse by vanishing the night before finals. No note. No explanation. Just gone. And with your parents already on edge, you knew the truth would knock them into the afterlife.

So you did the only thing you could: Stole his uniform, tied your hair back, lowered your voice, and walked straight into his elite all-boys’ academy like you belonged there.

The campus was chaos—boys yelling, sprinting, shoving, half-asleep from all-nighters. Perfect for blending in. You kept your head down, copying your brother’s walk, his slouch, even the way he pushed his bangs aside. The teachers didn’t bat an eye. His classmates were too stressed to notice anything strange.

Except one person.

Michael Kaiser.

Your brother’s sworn rival. Smug, golden-haired, sharp-eyed—he noticed everything. And from the first day, his gaze lingered on you too long. Like he was comparing, calculating, waiting for something to slip.

It took him exactly six days.

You were stuffing your books into your locker when an arm caged you in and Kaiser leaned down, a smirk ghosting his lips.

“So,” he murmured, voice low enough that only you could hear, “you’re not him.”

Your blood turned to ice as Kaiser got near and clicked his tongue. “Your brother walks like he owns the school. You walk like you’re trying not to get caught.” His eyes dragged slowly from your face to your posture. “And the way you tie your shoes? Cute. But wrong.”

He stepped closer, his breath warm against your ear. “I could tell the principal right now.”

Your stomach dropped. If he exposed you, everything was over—your parents, your brother, your plan.

But instead of calling a teacher over, Kaiser leaned his shoulder against the lockers, studying your panicked expression with far too much interest.

“…or,” he said, voice smooth, “you take a different deal.”

Kaiser’s smirk widened. “Stay in my dorm. My roommate moved out yesterday. I’m bored. And you—” his finger lightly tapped your forehead, “—are interesting. I want to know more about my rival’s sister.”

“And don’t worry, I don’t snitch,” he said simply. “And because the boys in your dorm talk too much. Someone else will figure it out soon. But with me?” His eyes glittered. “I keep secrets… well.”

He straightened, giving you space but not letting you escape the intensity of his stare.

“Decision time. Stay where you are and get caught…” He held up his dorm key, dangling it between two fingers. “Or come with me.”
