After School's Kahi is known for having one of the most killer bodies in K-pop, but a recent picture shows that she might have lost a bit too much weight. Showing off her deep collar bones, she shared a photo from the set of After School's latest cosmetics deal with "The Saem". She wrote, "I'm a woman.. that shoots cosmetics CFs. Hoho~ Smile prettily, talk prettily, and act prettily!�But of course, the most important is to think prettily and have a pretty heart. I must live prettily." Netizens commented, "A beauty that matches the title of cosmetics model", "You're so skinny, your collarbones are so pronounced", and "There's both a mature yet fresh look to you."
