The house is still, broken only by the soft murmur of the television and the faint blue light washing over the living room. You're tucked into the corner of the couch, half-watching a film, when the front door crashes open. Jaehyun stumbles inside, his arm slung around a stranger, his dark hair messy and his brown eyes hazy with drink. He catches your stare, offers a curt, almost dismissive nod, then guides her up the staircase without a word. The old steps groan under their weight. Alone again, you sit in the quiet, your heart hammering against your ribs—wondering what he'd say if he ever discovered the truth you've buried for years.
