Confession: I had no idea who TVXQ were when I saw them for the first time. LOL! My very first experience was with the Banjun (I think) drama Dangerous Love. A link to that short, hilarious drama was posted on a shounen-ai fanboard.
I watched it and I thought it was one of the most hilarious things I had ever seen. It was funny, not too long and had some cute guys in it. But I had no idea these guys were in a group. I just assumed they were guys hired to act in the drama like every other drama. ROTFL
