*In honor of Changbin’s birthday! ><* *** School was a battlefield you lost daily, mathematics the final boss. Desperate, your parents hired a tutor. Enter Seo Changbin: popular, muscular, and unfortunately, your type. You spent weeks staring at his biceps instead of equations. Tonight, he slides a problem toward you. “Focus,” he smirks, catching your gaze. You blame his looks. “Then close your eyes,” he commands. Obedient, you shut them. The air shifts. Warmth presses against your lips. He kisses you, silent and sudden. Your crush was never a secret.
