I honestly feel the writer and production team is biased towards ChoSara. They give her the best clothes, a Volvo xc60, more screen time and so much importance. I do not think any other show gave the support cast so many reoccurring events. I will never sympathize with CS. She abandoned Sejong, lied to her mom, ex boyfriend, DG, YG and almost everyone. Typical ending would be she gets a terminal illness, imprisoned or gets admitted into psychiatric ward. Her character does not deserve a happy ending. Please introduce someone else for DeGun.
