O Que Houve com a Secretária 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.

Secretary Kim grows closer to Sung Yeon knowing he was the one she was with when she was kidnapped. They visit a similar area they were kidnapped hoping it will help them remember fragments of their lost memory. The sight of Secretary Kim and Sung Yeon together drives Vice Chairman Lee mad to the point he professes his love to Secretary Kim once again. The tension between the two brothers heats up, while Gui Nam does everything he can to keep his ordeal a secret by following Ji Ah to the company retreat.

Young Joon invites her to his house for dinner. Although she has visited his house almost every day for the last eight years, Mi So feels totally different this time and gets very nervous. Young Joon awaits her with a surprise gift to make her heart melt. Later on, Young Joon and Mi So get to celebrate the opening ceremony of Yumyung Art Center. Now everyone’s eyes are on the Book Concert, and there Sung Yeon makes a disturbing speech. Mi So can’t help herself but worries about Young Joon only. What’s wrong with her?
