What's Wrong with Secretary Kim

After his personal assistant tells him that he’ll need to find a replacement, vice-chairman Lee Yeong-jun has trouble falling asleep.

Mi-so’s reaction to his proposal confounds Yeong-jun, but while others may think he’s brilliant and handsome, she just sees an impossible narcissist.

Yeong-jun takes Yu-sik’s advice to heart and tries to impress Mi-so with romance but is taken aback when he hears that she’s gone on a blind date.

Young Joon gets infuriated with jealousy after Mi So went to the blind date. They visit Yumung Group’s art center to expedite the opening, but accidentally get trapped in the library section and spend a romantic moment together. Meanwhile, Young Joon’s brother Sung Yeon returns to Korea after 3 years abroad to visit his family. However, something is not quite right the way Young Joon greets his long waited brother home.

Love and an ordinary way of life are not in Vice Chairman Lee’s repertoire, but he makes a valiant effort to profess his feelings to Mi So, his personal secretary, who feels otherwise. However, he continues on with his heart to fight off his elder brother, Sung Yeon, who suddenly appears in Mi So’s life, and finds a way to apologize to Mi So for his actions. Meanwhile, a wager on Mr. Ko suit rustles up the workplace.

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.
