Season 1

Han Eun Seong is an interpreter for French. However, she is not too happy with her job and complains to her best friend, Kim Rae Wan. On the other hand, Rae Wan, a painter, is going through a rough patch in his own work as well. Due to her broken water pipe, Eun Seong temporarily moves into Rae Wan’s place. Although they both act casually around each other as long-time friends, they both feel a bit awkward because of what happened two months ago.

Eun Seong and Rae Wan unwind at the end of the day by having a drink at Rae Wan's place. While drinking, they talk about the time when Rae Wan had to clean Eun Seong's poop in the toilet after she got drunk and left it there. She asks him if he felt anything while taking care of her mess, but Rae Wan re-sponds rather indifferently, saying that it's just poop. Eun Seong is hurt to see that he doesn't see her as a woman.

Eun Seong and Rae Wan share a passionate kiss once again, and things between them get awkward all over again. Although Rae Wan tries to deny it, he cannot help but have feelings for Eun Seong whenever he looks at her. Meanwhile, Rae Wan’s friend, Hee Nam, comes over to their place for dinner. Rae Wan is annoyed by how warmly Eun Seong treats his friend. Before leaving, Hee Nam tells Eun Seong that he is curious about her.

Eun Seong and Rae Wan get into a fight over a flat coke bottle that Rae Wan has been keeping ever since they slept with each other two months ago. She mentions his messy fridge, claiming that the fridge is exactly like his heart. In order for him to get over what happened between them, she tells him that he should empty out the fridge. Rae Wan tells her that the reason why his slump came was because of her and tells her to mind her own business.
