It takes a lot of effort to convince a good company to hire Eun Seol, a third-rate university graduate. However, she nails her interview and finds herself working for a wealthy and excellent looking boss. Her boss Ji Hun seems like the perfect man but has got a few issues with his family's company and simple presentations on stage. Not to worry, though, he's got a long line of assistants to help him out, Eun Seol being one of them.

Ji Hun is clearly giving Eun Seol a hard time to get her off his sleeves. He doesn't seem to recognize her, and she doesn't either. This doesn't seem right for Eun Seol, but she takes pride in her persistence, so she isn't backing down now. Luckily, her best friend Myung Ran is there for her after work, and Moo Won wants her in.

Eun Seol won everyone's hearts, but a visit of Ji Hun to her home one evening makes her lose the trust of her boss. Eun Seol is the only person Ji Hun trusts, but after being betrayed like that, his world is now a much more gloomy place to live in. Eun Seol still does her best to win his trust back, but it's going to be extra tough, knowing that he has no faith in anyone anymore.

Ji Hun and Eun Seol visit the theme park and bump into Na Yoon and Moo Won. Ji Hun and Moo Won exchange ladies to prove Ji Hun doesn't like Eun Seol. Ji Hun seems to have mixed feelings but deny it at all costs. A borderline lunatic, Na Yoon is back to swooning over Ji Hun, while Moo Won tries to take advantage of his time spent with Eun Seol. Ji Hun shields Eun Seol after being ambushed by the press, and both of their hearts are left unsure whether they should flutter.

After a night of staying up thinking of how Ji Hun can present his pitch without succumbing to his fear of crowds, Eun Seol hurriedly records his pitch to be presented to the company, which in turn brings them to a victory. Moo Won's mom isn't so pleased with her son's loss, so she's out to take revenge on Ji Hun. Hopefully, Eun Seol is able to get him through it too, or she's sure to lose her job instantly.

Eun Seol and Ji Hun talk about their feelings after they notice how they have been caring for each other, which leads them to a bumpy road. Eun Seol seems to care more about her feelings than her relationship with Ji Hun. Ji Hun, on the other hand, seems to be confused with his feelings, which also complicates the whole company. Hearsay spreads across the company of an alleged relationship, which gives Eun Seol a hard time, but she's determined to keep her job for as long as she can.
