I stumbled upon a video of these 2 incredibly sweet Korean twin girls from Sydney on Facebook. Their names are Janice and Sonia. They are 23 this year and with extremely beautiful voices to match.
If you are a little confused on who’s who, just know that Sonia is the one with the guitar.
I fully agree with Sze Kiat on this:
The best things comes in a pair
My words alone mean nothing, so let the video of them singing Tamia’s Officially Missing You do the job of turning you into fans:
I am absolutely blown away by their singing and I haven’t seen anyone else say otherwise. In the times that I am at my weakest, their voices would really energize my soul. Should they decide to start a professional career, I would be fully supportive of them.
