BSS leader Seok aka DK asks his seniors SEVENTEEN to promote the trio's latest song ‘CBZ (Prime Time)’

On January 8, 2025, BSS made their music comeback almost two years after their first single album, SECOND WIND, was released in 2023, with the album TELEPARTY. The album consists of three tracks, including ‘CBZ (Prime Time),’ Happy Alone, and Love Song.

Meanwhile, BSS members Hoshi, DK, and Seungkwan often joke that the unit is a junior group of SEVENTEEN and playfully treat them as their seniors. Following the release, DK, also known as Leader Seok of BSS, playfully asked his senior group SEVENTEEN to promote their comeback song through a text message.

The message was leaked by his fellow member Mingyu on Instagram Stories. The text read:

“SEVENTEEN sunbaenims, hello!!! Please help promote cbz a little ㅎ ㅎ - from, leader seok-”

DK reshared the story on his page with another hilarious response:

“Mingyu sunbaenim hahaha if you upload this i'll get embarrassed!!! i asked you to help promote cbz but what should i do when you promote my text message. Anyway, thank you so much!”
