Ko Hyeon-jeong takes on the role of Ma Yeo-jin the teacher. Her cold eyes and smile put on a different atmosphere from the usual teacher image. Her slick hair, black suit and black shoes earns her the name 'witch', 'gumiho' and 'psychopath'. "The Queen's Classroom" is about the events that happen between teacher Ma Yeo-jin and her class grade 6-3. She is fatally realistic and sharp. She becomes the authority of an unjust society and doesn't fear threats and hypo criticism instead of protecting her children. However, the class of 6-3 counters with her no matter what. They betray each other and reunite with each other, realizing what's real on the way. The set up of this drama is very different from the usual concept of teachers comforting their students with love. The process of Ma Yeo-jin creating a high wall between her and her kids and the kids who don't want to lose to her will eventually bring inspiration.

A drama about public defenders who take on the toughest cases with less than 1% chance of winning. Jang Hye Sung is a bold, sassy, thick-faced, comical female lawyer. She is a prickly edge, sharp tongue who doesn't have a bit of concept or manners and finds it hard to be enthusiastic about what she does. Cha Kwan Woo is a serious, passionate and macho former police officer who becomes a government lawyer. Meanwhile, Park Soo Ha is a 19 years old boy who has the ability or superpower to read the people's minds. Together they will team up to solve the cases no one else wants, cases that only have a one percent chance of being found innocent.
