Nice Guy actress, Park Si Yeon did not always look the way she did. Photos of Park Si Yeon were uploaded on an online community board recently from when she contested for the Miss Korea title in 2000. Netizens were quite surprised of her transformation. She looks just as lovely back then but the transformation is quite astounding, it's as if she's a totally different person now. Source: What do you think of Park Si Yeon's transformation?
