Gong Yoo is one of the best Kdrama actors. If you like him I recommend the 1st shop of Coffee Prince, a classic at this point (rom com). Goblin by the way was possibly the best Kdrama series in the last decade. For Zombies, Kingdom was nice but too short. They will have a second season next year though. Lately Netflix has been picking up many Kdrama series, so it's only a matter of time that they become even more popular in the West.
