Wonpil
Kim Won-pil (김원필), known as Wonpil, is the main vocalist, keyboardist, and visual of DAY6, the South Korean pop-rock group under JYP Entertainment. Born April 28, 1994, in Incheon, he debuted with the group on September 7, 2015. Within DAY6, Wonpil occupies a singular role: a classically trained pianist who became the melodic spine of a rock band, layering synth and keys beneath guitar-forward arrangements in a way that softened the group's edges without pulling them toward pure pop.
His solo debut arrived on February 7, 2022, with Pilmography, his first studio album and one of the most fully realized first solo records from any DAY6 member. The record was candid, emotionally exposed, and built around a sound that traced back to his piano training rather than the band dynamic. It sold over 100,000 copies.
In 2026, Wonpil released Unpiltered, his first mini-album, on March 30. The release marked a progression in his solo confidence: sharper in concept, broader in sonic range, and carrying the weight of an artist who has earned the space to experiment. The title plays on his name, a quiet statement that what you hear is unfiltered. His solo Spotify following has grown steadily to over 180,000 monthly listeners.
Wonpil also participates in Even of Day, the DAY6 sub-unit he shares with Young K and Dowoon.
