The start was fantastic! We have a strong story, a female lead (FL) that seems intelligent and ambitious, and a handsome male lead (ML) that is strong, sweet and has his own convictions. We also have good side characters. At the beginning, their stories seem to take almost equal attention as the main story, which makes sense as the series advances.
However, the development of the characters is so bad, specially the FL, who becomes very annoying (Min-a is a good actress, is the character who becomes insufferable).
Just when you think the FL is finally evolving and becoming less selfish, she strikes again with another tantrum. The perfect example is episode 10, when the ML really needs to hear from her that she loves him. Well, she didn’t not say it and in top of that, when she realises that Ji-wook was one of the kids her mother took care of, instead of asking for his reasons to hide the truth, she only explodes and says she is disgusted by him. The ML losses all his convictions and he becomes a total FL pleaser, he is immensely patient and always demonstrating his love for the FL, and she keeps being her annoying self.
the FL’s sister/friend and the Chairman’s son had a much better character development… it looks more and more as they were the main characters and not the originals.
