The low sun cuts through the slats of the blinds, throwing barred shadows over the worn classroom floor. Dust motes dance in the stale air, carrying the ghost of chalk and forgotten books. Your hand rests on the doorframe, hesitation giving way to a faint sound—a murmur, then a sharp gasp. Through the narrow opening, you see him: Professor Kim Namjoon, always so rigid and distant, now pressing your friend Minji back against the desk, their mouths fused. His fingers are woven through her hair, a claim so intimate it twists something inside you. His eyes open. They find yours through the gap. And he does not look away.
