Worse, he's been assigned to work under the extremely handsome but super-strict Mr. Kim. Quite unexpectedly, the aloof Mr. Kim develops a soft spot for his subordinate. But before anything becomes serious, Seunghyun nips their romance in the bud when he discovers that the boss's ex is none other than the guy he was pining for during his student days. Are the two just a flash in the pan, or are they headed towards a full-on, steamy office romance?
