On 27 December KST, SEVENTEEN’s sub-unit BSS (BooSeokSoon), composed of members Seungkwan, DK, and Hoshi, released a teaser video for their upcoming single "TELEPARTY" on HYBE's official YouTube channel.

In the teaser, the trio shares an inspiring message about embracing the youthful spirit, emphasizing that age doesn’t define youth — it’s all about knowing how to enjoy life. The video ends on an uplifting note with their declaration: "BSS will help create a world where we are all youthful. Youth is coming your way right now with BSS."

Set to drop on 8 January, "TELEPARTY" marks the group’s return following their "Second Wind" single album in February 2023, which featured the hit track "Fighting" with rapper Lee Young-ji.

Formed in 2018, BooSeokSoon takes its name from the members’ real names: Boo Seung-kwan, Lee Seok-min (DK), and Kwon Soon-young (Hoshi).

Meanwhile, SEVENTEEN is gearing up for their "Right Here" concert tour in the Philippines, scheduled from 18 to 19 January 2025, at the Philippine Sports Stadium in Bulacan.
