One is the coolest devil instructor in the Department of Finance and Economics, and the other is the most handsome new instructor who is two years below;
One looks cold and ruthless, but is actually as gentle as jade; the other is cheerful and funny, but is actually sensitive and suspicious;
One is despised by his strength, but the other has to succumb to his majesty.
But by chance, they were cast in the same drama "The Year One". What kind of sparks will collide between the two beautiful boys whose roles have been reversed? Is it brotherhood? Or kicked in the cabinet door? Who crosses the line first? Who was moved first?
