H1-KEY

H1-KEY is active as of 2026-11-15.

H1-KEY is known to be inspired by the English phrase "high key." The name was introduced as reflecting the group's aim of confident, healthy beauty. It is written with the number 1 as H1-KEY but pronounced simply as "high-key," which is worth remembering when searching.

H1-KEY debuted on January 5, 2022, with "Athletic Girl." As the title suggests, the group took its first steps with a healthy, energetic image that matched the direction behind its name. Fans celebrate the debut anniversary together around January 5 each year.

H1-KEY is currently managed by Choi Creative Lab. The group was originally formed by GLG and Sony Music Korea, and it now carries on its activities under Choi Creative Lab. For official news, check the agency's notices and H1-KEY's official channel announcements.

H1-KEY is currently a four-member group made up of Seoi, Riina, Hwiseo and Yel. Hwiseo joined the team in 2022. The four are active together, and official profiles for each member can be found on the agency's channels and the group's official accounts.

Known H1-KEY songs include the debut track "Athletic Girl," along with "Rose Blossom" and "Summer Was You." "Rose Blossom" in particular is often cited as the song that kept gaining love after its release and brought the group to a much wider audience.

"Rose Blossom" is the title track of H1-KEY's first mini album. Like a rose blooming in the gaps between city buildings, the song is known for portraying someone who keeps blossoming even in difficult circumstances. It is frequently introduced as one of the group's signature songs.

Building on a healthy, confident image, H1-KEY has released songs with messages that give listeners strength, such as "Rose Blossom." In 2025, "Summer Was You" used a guitar-driven band sound to look back on life's brightest moments through the lens of summer. Since debut, the group has broadened its range from energetic songs to more emotional ones.

A good starting point is the widely known "Rose Blossom." After that, going back to the debut song "Athletic Girl" and listening in release order lets you naturally feel how the group's music has changed over the years. Their live stage videos are worth watching too.

H1-KEY was formed by GLG and Sony Music Korea and debuted in 2022. Hwiseo joined that same year, creating the current four-member lineup. The group later moved to Choi Creative Lab and continues its activities there. Official news is available through the agency's channels.
