This show had so much potential. It started out very realistic and progressive but it quickly went down the drain with Jo Yi-SEO's character. It was too forced. It was highly discriminatory for the characters to say that toni was not korean because he did not look like it. It was not addressed later in the show. Also the word sociopath is used quite loosely. Jo Yi-Seo can be characterized as outspoken, rude and many other things. I'm quite disappointed.
