S1·E6 What's Wrong with Vice Chairman Lee?

Mi So requests a leave for the first time in her nine years of service. But she does not know what to do and where to go because she has never taken a day off before. Meanwhile, Young Joon, who can’t deal with Mi So’s absence, misses his secretary so dearly that he compromises to resolve his loneliness by joining Mi So on her day off. With great surprise, she gets a phone call from her blind date, Byung Heon, and finally hears about the boy whom she has been looking for.
