I watched this for Song Joong-ki and was pleasantly surprised at how good it is. It is about intelligent Kim Yoon-hee (Park Min-young) who, having lost her father early on, disguises as her sick brother to support her family. In a desperate financial situation, she was cajoled into illegally taking the national exams for another boy but was caught by Lee Seon Joon (Park Yoo Chun). Seon Joon persuades her into taking the exam for herself. They both pass the test and become roommates in Sungkyunkwan University. Sparks inevitably fly between them though her disguise make for some awkward moments, not to mention confusion on the part of Seon Joon.
Soon Joong-ki delights as flamboyant playboy Goo Yong Ha, one of Yoon-hee's close friends in the university.
