It’s no other than Choi Yeonjun of TXT. He’s BigHit’s legendary trainee. A singer, rapper, dancer and even a songwriter. He’s an all rounder so MOAs created the nickname 4th gen IT boy to hype Yeonjun up because he deserves the title so much.

The 4th Gen It Boy is the title fit for the one and only Choi Yeonjun of Tomorrow x Together. He is talented in all aspects of dancing, singing, and rapping. The eldest member of the group but is still an absolute cutie. Since their debut, MOAs (fandom) have already been calling him this title. Our little fox Yeonjun is really the best.
Welcome the 4th Gen It Boy, Choi Yeonjun!

With nicknames like “Hwang-vely” (AKA King-like) and Prince of the District given to him since pre-debut days, it’s no wonder why Hwang Hyunjin from Stray Kids is truly the 4th gen king. Not only is his name a fun coincidence to this title, but also his unique ability to constantly go viral and capture the hearts of non-Stays, other idols, and locals show how he is dominating the 4th generation of K-pop like the king he is.
As of now, he is currently the only 4th generation boy group idol to reach top 10 of GAON social charts, the 4th gen idol who has the highest view count for a fancam (6M+), the most Google searched 4th gen boy idol, the only 4th gen boy to have a library dedicated to him, and the 4th gen boy to go viral the most in terms of how many times and how much.

He has also produced and wrote a solo song called “Little Star”, as well as choreographed a contemporary dance to Billie Eilish’s When the Party’s Over.

Hyunjin is the main dancer, lead rapper, and center of 4th gen leader group, Stray Kids.
