S1, E2: 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 responds rather indifferently, saying that it's just poop. Eun Seong is hurt to see that he doesn't see her as a woman.
