Bouncy V-pop earworm, midtempo groove with bright synth plucks and snappy drums. Male vocals playful and flirty, stacked gang shouts on the “na na” hook. Verses stay minimal with bass and rim clicks; chorus blossoms with wide pads, rhythmic acoustic guitar chops, and airy backing “na na” harmonies. Short bridge strips to claps and vocal, then final chorus hits hardest with ad-libs.
