쿵쿵 (kung-kung) is a fun and expressive onomatopoeia. It's the Korean sound for a heart beating fast, similar to 'thump-thump' or 'ba-dump ba-dump' in English.
In "OVERDRIVE", TWS uses this sound to perfectly capture the feeling of a racing heart and the overwhelming excitement of having a crush. It's a simple but incredibly powerful word that makes you feel the singer's emotion as his heart goes 쿵쿵!
Buckle up, because “OVERDRIVE” is a high-octane confession of an instant, all-consuming crush. From the very first glance, TWS feels his temperature spike and his heart go 쿵쿵 as if his body is revving past the red line. Every lyric paints the rush of adrenaline: sweaty palms, racing thoughts, and the fear of being “found out,” yet secretly wishing the other person would notice the sparks flying. “Overdrive” is the perfect word for that moment when ordinary attraction shifts into turbo mode and you simply cannot slow down.
Underneath the electrifying beat lies a sweet promise: no matter the obstacles or even stormy weather, the singer is ready to risk it all as long as they are together. The song captures the thrill of losing control, the playful panic of realizing you can’t go back, and the joy of knowing that love can make even a rainy day feel sunny. It is a soundtrack for anyone who has ever felt their pulse race at the sight of someone special and thought, “Uh-oh, there goes my heart — and I kind of love it!”
