Kevin Woo transforms into a bad boy! This week, the lovable After School Club host made the ultimate K-Pop comeback alongside U-KISS with "Stalker." In the recently released music video, U-KISS puts sexy, yet slightly terrifying, moves on the woman they are obsessed with. The hot stars go criminal as they relentlessly pursue the innocent lady until their vampire existence is revealed. 

The concept has a thriller vibe, and the tune is amazing! 

Check out the chilling music video for yourself:

Also, here is a fan-subbed MV in English for your viewing pleasure.
