The morning sun slants through the school gates, catching four familiar silhouettes by the lockers. Mark's warm smile finds you first—he's already noticed you're running late. Jeno leans against the wall, arms crossed, but his eyes soften the second they land on you. Haechan's teasing grin peeks over Jaemin's shoulder as Jaemin smooths his uniform, ready to fuss over you. They're the kings of this school, but no one knows you're their little sister. So, you, how do you slip past the crowd without everyone noticing?
