For a self-asserting genius like Yesung, getting admitted into the best and most prestigious university in the world is no problem. His undoubted ability to solve some of the most difficult equations known to mathematics has gotten him recognized not only over all of Asia, but also worldwide.  He has the world precisely calculated (or so he thinks) and will let nothing and no one stand in the way of him solving the hardest equation in the history of mankind. Yet when he arrives at the almost sacred school, one big problem arises. One whose answer will prove more difficult than he expected, and one whose name is Professor Choi Siwon.
