Jeon Yu Jin released the music video for “Childlike Slumber” (어린잠) through 1theK on 23 October 2025. The Korean title pairs a plain adjective with an ordinary noun, and the English rendering supplied by the label is a translation rather than a separate title.

Trot, and why it sits beside K-pop

Jeon Yu Jin came up through trot, a Korean popular style that predates K-pop by decades and never went away. Trot has its own vocal technique, its own veteran circuit of theatre shows and regional festivals, and—since the late 2010s—its own televised audition franchises, which is how most of the current young generation of singers arrived. Foreign listeners often meet trot only as a novelty, but in Korea it holds a parallel industry: separate charts, separate broadcast slots, separate award categories. A singer can be a household name there while barely registering on the idol-focused coverage that reaches the rest of the world.

About this release

The video was published on the 1theK channel, which distributes music videos for a wide range of Korean labels rather than belonging to any one of them. The official description carries no producer, writer or featured-artist credits, and names no parent album or EP—so the release format is not stated on the video page itself. Anything beyond the title and date would be guesswork.

Watching from outside Korea

어린잠 is the Korean title of this track. Watch the video on this page; writing and arrangement credits are only established when explicitly provided in the release details, rather than inferred from the artist’s name.
