Krystal and model Ahn Jae Hyun cozy up for 'Puma' f(x)'s Krystal and model Ahn Jae Hyun cozied up as a couple for sportswear brand 'Puma'! The two got cuddly on a chair with their arms wrapped around each other and looked like a cute campus couple in their preppy outfits. If Krystal's smile wasn't enough to win you over, Ahn Jae Hyun threw in a wink which added to the sexy charms shown in the pictorial. The brand's marketing director commented, "In order to raise awareness of 'Puma's unique color to young consumers, Krystal and Ahn Jae Hyun have been chosen as the brand models. Through [their promotion of] Puma's various campaigns and modeling of products, we anticipate a synergy effect." Although those still under the spell of the recently concluded drama 'Heirs' might be more appreciative of a pairing between the idol and CNBLUE's Minhyuk, it's hard to deny that she and Ahn Jae Hyun look good together as well!
