NCT's Mark Lee has dropped the first teaser photos for his upcoming single “Fratskiya,” featuring Korean rapper Lee Young Ji.

The track scheduled to release on 16 December serves as a pre-release for Mark's highly anticipated first solo album, set to drop in April 2025.

SM Entertainment announced on 9 December the postponement of Mark’s album, originally slated for February, citing a commitment to enhancing the album's quality.

"We sincerely apologize to fans who have been waiting for Mark's solo album. We will work hard to prepare and return with an even better album," the statement read.
