Although RAINBOW has disbanded, the members still have a strong bond of friendship. They still often spend time together. As Ji-sook has posted on her Instagram, the girls got together in a restaurant.


From the video above, it looks like Ji-sook wants to sing when she turns around, but actually, she just drinks a cup of coffee.


She always looks gorgeous! Even though it’s just an ordinary selfie but she still looks charming and beautiful.


At first glance, there is only an ordinary calendar and a miniature in the picture posted by Ji-sook. But it is not just an ordinary calendar, it is Dmost Entertainment calendar.


Cold weather does not stop Ji-sook to look beautiful! With her warm jacket and red nose, she still captivates people and they like her photo.

The photo was captured when she attended the 2018 Mnet Asian Music Awards ceremony in Japan.
