My Bias : Song Ji Eun.

     Don't ask me why because from the first time I see Jieun, I already fell in love with her (I am a girl BTW, lol). She is really quiet and shy, but she has powerful voice as she is main vocal in SECRET. She is the one who brought me to know SECRET more, and eventually become SECRETTIME (SeTi). I like all of her ballad and RnB songs (Going Crazy, False Hope, Don't Look At Me Like That, etc).

Most Favorite Pairing in SECRET : Jieun-Hana

Most Favorite SECRET's song : 3 Years 6 Months (which brings me to tears).
