You get the idea about the drama from the "Title" itself.

However, the idea of how his journey begins as a Zombie is pretty fun and interesting. I've watched many Zombie movies and dramas, but this seems different on a whole level. The little comedy scenes that they throw at you when things get serious is quite boosting for the interest. Choi Jin Hyuk has done a pretty great job with his acting. The couple looks great together, their chemistry wasn't full of romance but still good enough.

Overall it's a pretty interesting drama.
