Korean indie rock breakup ballad, clean electric guitar arpeggios opening with the solo vocal, subtle piano, warm bass and live drums; warm husky male vocal with natural Korean phrasing, restrained and conversational verses; natural, intimate vocal delivery and close drum sound; 78 BPM, bittersweet sway, a memorable melodic chorus and gradually building pre-choruses, a sparse bridge, then a raw emotional final chorus and softened outro.
