I started this drama when it first came out and, although i wasn't sure I would enjoy a drama like that,as a plot like this isnt usually my cup of tea,i enjoyed it and I can easily say I regret nothing. As you keep watching you start to discover the dark side of each character,their motives and ambitions so you're always caught off guard. After a few episodes it was really hard for me to wait for the next episode. Another thing I liked was the relationship between the two main characters. They develop a strong friendship, and the female lead doesn't work as a love interest. We see how they get close and their moments together are very heartwarming. Overall I reallt enjoyed this drama,it was a well thought out plot, good acting and a lot of drama.
