Overall I feel that to watch this show, you must have a certain level of maturity and open-mindedness. If not, it would be really difficult to see this show to the end due to the nature of this story. As you probably would have already known, it is mainly revolved around infidelity thus it can cause feelings of frustration and anger while watching. This drama seems to focus more on the emotions and feelings of the characters, which leads to relatively little plot development in each episode. Despite that, I would say that this show is really interesting and emotional. It can be difficult to comprehend the reasons why various characters think and behave in a certain way but I believe that it was intentional. As a fan of Lee Siyoung, I feel that she managed to portray Il Ri's crazier younger and older self well. She definitely evoked a full spectrum of emotions throughout the show. Uhm Taewoong, Lee Soohyuk and the other minor characters were also great! They fit their characters well and I really have no complains, so thumbs up to the casting directors! A special mention goes to Lee Yeong Ran (Hee Tae's mother). I feel that she deserves more praise for her superb acting!
