What it's about: There's a good chance that if you're a K-drama fan, then you've watched (or at least heard of) Guardian before, but if you haven't yet, then this is your chance to do so. Also known as Goblin, the show centers on Kim Shin (Gong Yoo), a Goryeo dynasty general who is wrongfully killed and sentenced to live forever as a Goblin. The only way he can truly be freed from his immortal coil is to have the sword in the center of his chest removed, but the only person who can remove it from his chest is his bride. Enter Ji Eun-tak (Kim Go-eun), a sweet-as-can-be high schooler who has some special powers of her own. Then toss in a socially awkward grim reaper (Lee Dong-wook); a cuddly, rich heir as the Goblin's assistant (Yook Sung-jae); and a cheeky restaurant owner (Yoo In-na), and the result is a charming, emotional drama you'll find yourself rewatching over and over again.
