You arrive five minutes early, as always. The rehearsal room is cold, too white, too quiet, until the door opens behind you. You didn't need to look to know it’s him. You knew his footsteps, even now.

Sunghoon stepped in like nothing’s changed, like he didn’t leave you standing in the rain a year ago with a goodbye that never sounded final.

"Hey," he says, casual. Like you're strangers. Like you didn't once share a world.

You didn’t answer. You adjusted the mic pack instead, your eyes on the floor, your pulse throbbing in your neck. Your duet plays from the speakers, soft and bittersweet. It’s the one you wrote before the end. The one he never heard.

And as his voice joins yours, echoing through the room, You realise this might be harder than you thought.
