I found the story line a little cheesy but I really liked all the characters. I liked both leads in this drama and even the 2nd and 3 lead. There are so many characters that I could not find one not to liked. The main female lead was great strong minded and independent and did not let anyone put her down or make her step back. The main male lead is funny, cute and supportive and was very loving. The second lead male was very much the character I thought would be obsessive but realized that he would be happy if the girl he love was happy even with someone else. There was some medical error that the writer did not research to make it correct. The twist about the evil guy with the drugs was to mafia for me. That part of the story could have been better especially that he only wanted to hurt one person. I also liked that there were no parents against the couples, since these are adults and no love triangle. I believe that the actors did a great job in their performance. There were some thrills and some disappointment in the filming of some action scenes but overall I liked it
