This pictorial makes me happy but the surprise cameo news makes me even happier. A-list young actor Yoo Ah In plays up his boyish and brooding side in a recent spread for Vogue Korea, a visual reminder of how impressive his meteoric success has been considering he’s still so young. He’s currently starring in the Mon-Tues ratings leader sageuk drama Six Flying Dragons, and will likely enlist for the military after it wraps next month. But he’ll be seen onscreen in a different capacity soon, jumping networks to KBS the Wed-Thurs drama Descendants of the Sun starring Song Hye Kyo and Song Joong Ki. The drama just started airing last week and Yoo Ah In’s cameo won’t appear until the latter half of the drama. He’s actually really good friends with Song Hye Kyo as well as Song Joong Ki thanks to their unforgettable bromance in Sungkyunkwan Scandal.
