The writers should have hired another actress to portray the Femal Lead. I just found out that Hong So Jo is the real name of the FL. I would not blame the writers or directors for her poor portrayal of the role because there are people who do not have charisma to be likable.
To be honest, the drama has so much potential but I always have to skip that scenes of the FL. I do not understand her acting. I feel like she is not even poor the way she's portraying her role. She does not look like I should pity her that is why I did not get the fuss between the ML and the second ML. Either very poor writing or very poor acting from her.
