Jugglers

Jwa Yuni is a competent assistant of Managing Director Bong of YB Headquarters. She tries her best to cover for her boss' affair rather than taking care of her own love life and ends up getting herself in trouble. Nam Chiwon, who is uninterested in other people's business, keeps running into Yuni and finds her odd and unpleasant.

Yuni is humiliated by Bong's wife who is mistakenly convinced that Yuni is Bong's mistress. While giving an orientation to the new assistants, Yuni finds out that there is a rumor about her spreading throughout the company. And she ends up being on the waiting list to be assigned. Meanwhile, Jeongae who seems to have a good life as a housewife comes out with her secret to the three jugglers.

Chiwon is bothered by Yuni who keeps intruding his workspace saying that she would stick to him like glue. Yul offers Yuni a deal to get him a new assistant just like her in exchange for an important information about Chiwon. Jeongae stays with Yuni after she runs away from the loan shark. Meanwhile, Yuni's mother asks Kyungrye to look for a young man to move in as Yuni's upstairs tenant.

Although Chiwon is Yuni's boss at work, their positions are reversed as they become the tenant and landlord. Yuni gets excited about the situation and even gives him a list of the house rules, but she ends up with more annoying tasks. Meanwhile, Yuni tries to get Jeongae hired as Yul's new assistant by posing her as her younger sister.

Yuni starts to get to know about Chiwon through the questionnaire he filled out and debates with herself if she should hand it to Sangmoo. On the night Chiwon drinks with Yul, someone breaks into Yuni's basement and Yuni asks Chiwon for help. Meanwhile, Yuni tries everything to get Chiwon to participate in YB's event where they pick the best boss to be promoted.

Yuni feels terrible after Chiwon knocks over the birthday cake she prepared for him in front of everyone. On top of that, she finds out that she has to work with her first love Changsu on the same team. Chiwon starts to open his mind to Yuni while feeling sorry to her. Yul gives a mission to Jeongae to get him a limited edition shoes in the frigid winter.
