This is Kpop.

Kpop is the abbreviation of Korean Pop (케이팝). It began with the boy band H.O.T. in 1996 and then TVXQ and BoA started a new generation of K-pop idols that broke the music genre into the neighboring Japanese market and continue to popularize K-pop internationally today through social media.

Kpop includes different kinds of groups.

The sexy or mature group like AOA or 2pm

There is also the strange one like Red Velvet or Nct

And the badass one like Blackpink or Big Bang
