Headphones block out the noise. The earsplitting noises of life are replaced with beats, voices, the strum of a guitar. Things that aren't easy to understand, per se, but they are controllable, calming. Kyungsoo lives with a pair of black headphones perched on his head, filling his ears with music and blocking out the outside. He's never had a reason to let something into his heart other than music. And he's fine with that. But one day he finds something intriguing. Maybe he'll slide the headphones down, around his neck, and let this newfound interest in. Just for a moment.
