Shen Yanci (28), associate professor of the Department of Finance at Ningshi University of Finance and Economics, is known for his cold and strict appearance. He wears dark shirts and silver-rimmed glasses all year round. He is privately called a "walking textbook" by students. Senior Lin Shuyue (22 years old) appears to be an ordinary accounting major, but in fact she is burdened with huge debts. She attends classes during the day and plays guitar in a bar at night. She is a broken girl with a sense of alienation.
