The 'Produce 101' season 2 trainee will be debuting as a solo artist in September, and the teaser shows a bunch of consonants as hints to who will be featuring in albums. The highlighted '???' is for Jung Se Woon himself, while the others are people who will be participating in his debut, which will be divided into two parts. Producers such as Primary (?????), Groovy Room (????), Brother Su (????), Mind U (????), as well as Kiggen, Duble Sidekick, and Joombas have been confirmed for his debut album. Yoo Seung Woo (???) and Sik-K (???) will also be featuring in his songs. 

But most excitingly for 'Produce 101's Starship fans, it's been confirmed that the '??' in the teaser is not MONSTA X's Kihyun but fellow 'Produce 101' trainee Lee Kwang Hyun! While the pair are not debuting together as some fans hoped, Lee Kwang Hyun will be featuring in the debut album.
