I'm a guy and I listen to both.
For VK I mainly listen to dir en grey, but I'm also an MM fan and like both the glam and vk.
I was pulled into kpop by listening to a few snsd songs. Then I liked a few other kpop songs that started releasing by other bands also. Like B.A.P - No Mercy, or Sexy free and single by sj.
I can't speak either of the languages yet (and I plan on learning both partially because of the music and partially to visit those countries later in life), but how can you not like songs like the final, akuro no oka, saku, clever sleazoid, drain away, aint afraid to die.... Even if you cannot directly understand it (I have been able to know what is being said when it is being said by memory though).
