Very interesting show

I was expecting a horror show but this actually centers more around the occupation of Korea by Japan in the 1940s. The Japanese are experimenting on people at a hospital and end up creating a very deadly monster. Mostly, this is about fighting oppression and the maturing of the protagonist from a cocky entrepreneur to a respectable leader of the resistance.

It manages to squeeze in romance, comedy, drama, sci-fi, action, and horror. The story was good, and I thought the characters were interesting enough to care about.

I was fine until the very ending scene. I have no idea what it meant, and what was going on. If anyone watches it, please let me know if you can figure it out.
