Mark loves doing sports, so naturally he's glad to be allowed to receive education at the nation's most renowned sports college. But the college has a problem: its academic average is too low. The solution: the school management recruits a bunch of brainy kids who are supposed to solve the problem. But school regulations say they still have to pass the sports entrance test. To prepare and train them for the test, every brainy aspirant is provided with a student trainer. Mark is responsible for Park Jinyoung, who is grumpy, stubborn, and an athletic disaster.
