On April 24, GLAY announced the release of the band's 30th anniversary single, "whodunit - GLAY × JAY(ENHYPEN) -". Jay took part in the collaboration as a featuring artist, writing his own lyrics for the single. While Jay previously participated as a lyricist for ENHYPEN's 5th mini album title track "Sweet Venom", this will mark his first attempt at writing lyrics in Japanese.
Meanwhile, ENHYPEN will be greeting fans in the United States from April through May for the North American leg of their 'Fate Plus' world tour.
