H1-KEY has a new music video out, and this one arrived through 1theK rather than the group's own channel. The MV for "We're Happy" (행복합니다) went up at 18:00 KST on August 22, 2026, giving us both the English and Korean versions of the title right in the upload.
If you're not familiar with how 1theK fits into releases like this, the channel spells it out in its own description: it's an official distribution channel for the MV, and music shows will count the views logged here too. So this isn't a fan reupload or a lesser copy sitting off to the side, it's part of the release itself.
The video clocks in at 3 minutes and 7 seconds, which is the only technical detail we have to go on beyond the title and channel notice. There's no additional producer or credit information listed in the description, so we're not going to guess at who else worked on it.
For anyone tracking H1-KEY, this is your notification that "We're Happy" is officially out and watchable right now. We'll keep an eye on the group's channels for anything further tied to this release.
