Seventeen has entered the countdown to their comeback.

On the 29th at 10 PM (Korean time), Seventeen posted the promotional scheduler for their fifth full-length album 'HAPPY BURSTDAY' on their official SNS.

They hinted at a variety of content, showcasing three versions of concept photos and films. Following that, the tracklist and highlight medley will be released sequentially.

They are celebrating their 10th debut anniversary, having debuted on May 26, 2015. They will unveil their new album and title track music video on the upcoming 26th of next month.

They have also prepared a birthday party, hosting the 'B-DAY PARTY' from the 23rd to the 25th of next month. The 'BURST Stage' will take place at the Jamseongyo Bridge in Seoul.

In addition, they will satisfy fans with even richer content, noting in the scheduler that "and more to come."

The fresh promotion maximizes immersion, capturing the process of Carats (the fandom) receiving Seventeen's party invitation and heading to the venue through three videos.

The agency stated, "(In the promotional video) Carats arrive at the party venue," urging fans to "watch for what kind of spectacle awaits them."

'HAPPY BURSTDAY' combines the English words for birthday and burst, embodying their determination to be reborn as a new Seventeen.

Meanwhile, Seventeen recently held a fan meeting at the Kyocera Dome Osaka in Japan. They will head to Saitama Super Arena on the 10th and 11th of next month.
