Na-yul is worn out from doing the work of three people while constantly cleaning up after a careless junior colleague. Fed up after a night of frustration, she storms into the office of CEO Kwon Si-jin, whom she considers the most insufferable man she knows. Instead of the confrontation she expected, she finds him acting strangely during late-night overtime, leaving the two of them staring at each other in a suddenly charged silence.
