The actors and actresses all did a good job at portraying each characters, especially Yoon Shi Yoon. He is capable of acting two completely opposite characters and personalities. The actors who played the villains and the victims did such a good job too.

The storyline is good and interesting, I love seeing the misfortunate twin brother got switched placed from the fortunate judge twin brother. I also love seeing how FL and her sister supported each other, although I didn't quite understand why FL's sister has to leave.

However, there are some areas writers needs to improve. The ending seems to be cut short and rushed, and the villains of the drama (the three "conglomerate" criminals, the corrupt lawyer, and pervert prosecutor) supposed to be punished accordingly, but it doesn't show in the end or anywhere in the drama (idk about y'all, but until those evils get fair sentencing, I feel like as an audience of this drama, I feel somewhat unsatisfied). The ending only shows FL got off the "falsely accused/character defamation" suit, but I think the writers should've included the downfall of the perverted prosecutor. I think by showing the downfall of evil characters brings a good message to society on how karma works.
