I find this drama entertaining yet frustrating. The seemingly selfless acts of Jung-suh to back away from Song-ju is in fact very selfish. Also, if she truely loves Jong-su why would she want to saddle him with her crazy step sister? So "stepping aside" to allow a marriage to take place that will no doubt result in total heartbreak, chaos and stress is not an act of selflessness. It's stupid! That said how presumptuous of her to assume that if she steps aside he would EVEN WANT to marry her??? AND WHY would anyone want to marry a man who's heart is attached to someone else? Very strange! I also find it strange that a personal conflict in one's life can bankrupt a multi-million, global corporation or that one working in said corp. would be totally broke in less than a weeks time of ending employment. Don't get me started on Jung-suh's father... he hears that is child was beaten by the step mom on a daily basis and nothing comes out of his mouth? I know, lots of questions and comments for a drama. Still.
