Second Generation K-Pop Idols Are Back To Dominate 2021

Old K-Pop fans, 2021 is ours!

It’s been so long since we saw news (lots of it) of second generation k-pop idols releasing new music, but 2021 is finally our year.

Now that many of the second generation idols specially the men, are out from the military, it is expected that their groups will be together again to promote actively. There are also few female idols that will return to represent second generation girl groups.

K-Pop nowadays are composed of 4th generation idols and some from the 3rd generation and very few from the 2nd generation. Most idols from the 2nd/2.5 generation are either serving in the military, pursuing a new endeavor (acting, solo career, variety, etc) or sadly have parted ways (disbanded). There are some inactive groups as well with members signed under different agencies.

But there’s hope this year, yeorobun! 2021 = OG k-pop idols’ domination.

It will definitely be a festive this year and we can’t wait for new k-pop fans to discover our beloved 2nd gen ♡

Here are some of the confirmed ones and also those who are reportedly returning with new music.



Yunho started the 2nd generation domination with the release of his solo comeback album entitled “Noir” last January 18, 2021. TVXQ is also confirmed to be the main MCs of upcoming Mnet program “Kingdom”. Fans are expecting a comeback from the duo this year as it’s been so long since the two released music together.
