Found some interesting photos of Rainbow's Ji Sook to share here!
Rainbow's members were practicing "Not Your Girl" in the studio as you can see in the photo.However,member Ji Sook was spotted constantly lifting up her shirt,it seems like something has happened to her stomach.
Since chocolate ABS is a hot term nowadays,i am wondering whether she is checking whether she has chocolate ABS or not after training for such a long hours,such a cute action!!
