하트번 (Heartburn)
선미
Sunmi's "하트번 (Heartburn)" is summer pop with a knife hidden in the fruit basket — bright disco-funk guitar, a bouncing bass line, and handclaps that suggest a beach party, all deployed to describe a love that physically hurts. That contrast is the whole design: the production is sun-drenched and major-key while the lyric describes the burning in the chest that won't go away, indigestion as romantic metaphor, wanting someone until it becomes a symptom. Sunmi sings it with her characteristic dry, slightly hollow tone — she never oversings, letting a flat affect sit against the cheerful arrangement so the irony lands. Her delivery in the verses is almost conversational, then the chorus opens into a wide, breezy hook that feels like relief without actually resolving anything. Culturally this sits in the run where Sunmi established herself as K-pop's great melancholic entertainer, writing her own material and building a persona out of glamour worn like armor. It's music for driving to the water with someone you shouldn't be driving to the water with, or for dancing alone in a kitchen while feeling genuinely awful. The emotional landscape is deliberately unresolved — pleasure and ache refusing to separate, which is exactly the condition the title names.
