My first k-pop band was Super Junior, but at that time they were quite new in the k-pop industry. I think it was year 2006 or early 2007 when I first found them and they had only released their debut album: SuperJunior05 (Twins).
I also remember that their subgroup Super Junior K.R.Y was formed and they released their first song "The One I Love", which I loved! I think I already listened to Super Junior when their trot-group Super Junior T was formed and at first I didn't really like their song Rokugo, but then it became one of my favorites somehow. I also watched almost every episode of their reality show Super Junior Full House and some other early reality shows with them.
Gee.. now feel all nostalgic, haha! xD
Nowadays I barely listen to Super Junior anymore, but I cherish the years I spent loving them.
