What was my "gateway" drama?

Short answer: KPOP Extreme Survival on Netflix (I am so embarrassed.)

Long answer: I am a long term/huge fan of Survivor (US version) to the point where I listen to podcasts about it. One of my favorite podcasts began reviewing the Korean game show The Genius which then led me to Netflix to watch more Korean shows. My first KDrama was  KPOP Extreme Survival (singing, Baby, say yes!). Then Boys Over Flowers, You're Beautiful and a premium subscription to Dramafever makes me side eye my cable payment each month.
