If you watch the video below,you can't really differentiate between them,they are like twins,i think it is due to their hairstyle,they look almost the same with the hairstyle.
Just look at the photo above,they look quite similar right?Both of them appeared on Star King aired yesterday and had fun on the show.All the guests attacked Kang Ho Dong on the show and when it was Eun Jung's turn to hit Ho Dong,she was like embarrassed....So cute!!
Anyway,please watch the video below!!
