On July 25th, After School's Jungah shared a new selca taken with fellow 'red unit' groupmate, Nana! Through her Twitter, she wrote, "Look at the small muscle in my arm." The picture was actually taken by a friend, so Jungah retweeted the link to share with her fans. Taken from the set of their music video for "In the Night Sky", Nana is seen rocking an Indian headpiece while Jungah shows off her toned arm beside her. Netizens commented, "Both so gorgeous", and "We're in love with your new song!" Source + Photos: OSEN via Nate
