겨울잠 (그 해 우리는)

A sparse piano line opens like frost forming on glass — delicate, unhurried, almost reluctant to disturb the silence. The arrangement stays skeletal throughout, a single acoustic instrument carrying the weight of an entire season. IU's voice here is stripped to its most vulnerable register, barely above a whisper in places, as though she's narrating something she hasn't quite processed yet. There's a quality of suspension to it — not sadness exactly, but the particular stillness of someone who has gone inward, hibernating from a feeling too large to confront. The song captures the sensation of winter not as cold or harsh but as a pause, a held breath. Lyrically it circles around the idea of someone tucking away a memory to protect themselves from it, the way animals burrow before the freeze. It belongs to the quietest possible version of late night — the kind when snow has muffled the city and you're sitting alone with something unresolved, not ready to let it go but not strong enough to face it either. For fans of the drama it scores, it functions almost as internal monologue, the gap between what characters say and what they feel.
