The fact that woo yeon end up with Lee soo is somewhat childish. I mean both of the main characters are CHILDISH! One is playgirl and the other is a JERK. How in the world she starts a relationship with the CEO while having so much feelings toward Lee Soo?!?! It makes the main character looks bad. No matter how nice woo yeon treat the CEO after that. It only brings pain toward him. Plus, we can see how hardworking CEO is to develop their relationship but that dumb girl is so STUPID! Lee Soo only know how to beg for love. The story would be my favourite if woo yeon end up with CEO. After all the quotes they are saying which makes us feel like if we are too late to realize our feeling then it will be over. At the end they make them together. So what's the point? Try to imagine woo yeon and CEO together at the end. It will makes woo yeon character a bit better after all what she's been through. Indeed beautiful ending such of this drama is hateful.
