I saw a perf of Secret World (the one in pink) and found they were great singers
...at that time I was a big fan of Wonder Girls (I always love them but less tha KARA)
So I decided to see more of them and watch almost all their perf since their debut
and I was impressed by their improvement with stage !
Then, I learn to know their personality and discover they are all sweet, nice, funny and natural persons.
During their break I understood I much I loved them and how big fan I become lol.
