H1-KEY Sets Nov. 13 Return With Unbelievable After 8 Months Away

H1-KEY will release the new digital single "Unbelievable" on November 13 at 6 p.m. KST, ending an eight-month gap since the group's last release. Seoi, Riina, Hwiseo and Yel are promising a musical transformation this time around.

The last release was the fifth mini album LOVECHAPTER in March, whose title track "To. My First Love" leaned into a high-teen romance mood. The label has framed the new single as a change of direction from that sound, though it has not yet revealed what the shift involves.

The group has built its identity on stories of youth, through songs such as "It Was Summer," "Rose Bloomed Between Buildings," "The World Isn't Like a Movie" and "Let's Heat Up." That history is why the message of the new single is drawing attention.

A busy year on stage

H1-KEY spent 2026 widening its fanbase through live appearances, bringing its bright, energetic stage presence to Waterbomb Seoul 2026 and the 2026 Hello DDC Festival, along with a run of university festivals. The group also wrapped up its first solo fan meeting in Japan.

Outside of music, the members were appointed official ambassadors of the IEF 2026 International e-Sports Festival and sang on a remake of the volunteer-service song "Happiness." Heading into the comeback, those activities give the group a broader footing than it had in March.
