When a high school girl dies mysteriously, her friends decide to investigate the cause of her death. The second season has a similar focus to the first, dealing with current social issues faced by the youth both at school and beyond: friendships, familiy problems, pregnancy and educational corruption.
A drama about school life that sheds light on the serious issue of cheating and falsifying grades, as well as the stress of entrance exams at ruthlessly competitive South Korean high schools.
