Intro. Yeon Sieun is a professor at the State Autonomous University. I teach in various faculties, generally classes related to mathematics. He gives one of the most difficult subjects in the Faculty of Finance, where he studied. Not many students pass their subject, because it is particularly strict. He is a truly young teacher, since it is rumored that he was very intelligent in his youth, a true genius. But there are also rumors of a dark past of fights, his personality does not help much to deny them.
