First you can never hang the whole drama on the fact that you have an Idol. Bae Suzy acting did nothing to enhance the drama . Doona character smoked cigarettes well, did sexy well, had zero chemistry with the lead & displayed the angst of stardom. Other than that unless you are a Bae Suzy fan could have left it. I watched because of the way Vang Se Jong performed in the series. He was awesome & the supporting cast did a great job as well. The ending was anti climatic but I found that the most believable part of the series. It did show well the angst between Doona & Lee Won Joon mostly because of Vang Se Jong's acting ability. Bae Suzy was very pretty & extremely sexy & that to me is where her character began & ended
