I Got into KPOP early 2015. First MV I've ever watched/listened to was Bigbang's Fantastic Baby.
At the time, I was really into Rock Bands and had never heard any Korean songs or Dramas. Over the Course of a week or two, I started listening to Kpop and listened to a variety of people and groups. These are my favorites : First, B.A.P, my fav KPOP group:

Then Epik High, a strange but unique group that I grew to love.

Then Ailee, Jang Wooyoung, and Henry Lau

And Of Course, JinWoon!

I Got into KDramas because of a Try Guy's Episode (Buzzfeed).

My First KDrama was The Heirs, which got me into other series, despite how I realized that the Heirs weren't that good. Led me to many, many series that I enjoyed. For Example, Five Fingers

& Love Me If You Dare! (My Favorite)

But, I of course still enjoy American TV shows, and movies, however the American music is another story. For Music, I depend on Kpop and Jrock, like One Ok Rock.

Remember, before Kpop and Jrock, I was a fan of groups like, Black Veil Brides, Sleeping With Sirens, Linkin Park, Altessa, Pierce the Veil, and My Chemical Romance.

Woah! That hair Doe Jake!
