Boy band BoyNextDoor uploaded a video letter to its fans on Tuesday titled "400 Years."

Uploaded on the band's YouTube channel, the video shares the name with the band's song dedicated to Onedoor, its official fan club.

"400 Years" has not yet been released on music streaming platforms.

All members participated in writing the song's lyrics, and members Myung Jae-hyun, Taesan and Woonhak participated in composing the song.

"400 Years" is a song that thanks Onedoor and the love the fans have given to the band, the agency said in a press release.

The song's title embodies the band's wish to stay together with its fans for a long time, according to the agency.

"As 400 years hold a special meaning to us, we won't let that time pass by without any purpose," the band said in the comment section of the video.

The video also featured hand-written letters from the members.

"We would like to say, 'Let's be together just for 400 years,' instead of using the word 'eternity,' which seems far away."

BoyNextDoor debuted in May 2023 as a six-member boy band under rapper and producer ZICO's self-established agency, KOZ Entertainment.

KOZ Entertainment is currently under HYBE. The band members are Sungho, Riwoo, Myung Jae-hyun, Taesan, Leehan and Woonhak.

The band released its debut single "WHO!" on May 30 and its first EP "WHY.." on Sept. 4 last year.
