In a dark bedroom a couple, faces in shadow, roll around on a rumpled bed. The man takes off his shirt and pants, and they pull the covers over themselves. Rawr.
A few evenings earlier, Se-ah leaves the ladies' wine party, and Yeo-reum follows her out to the street. He returns the envelope she previously gave to him, but she says that she already knows everything she wants to know, and tries to hand it back to him.
Ki-tae and Jang-mi see the end of this exchange, and Ki-tae jumps to the right conclusion about Se-ah, while Jang-mi jumps to the wrong one about Yeo-reum. Jang-mi fixes betrayed eyes on Yeo-reum and says that she must have been the only one with feelings again, and escapes before he can explain. He tries to follow her but Ki-tae stops him, asking Se-ah if it's fun to play with people's emotions.
He follows Jang-mi and they end up drinking soju at a pojongmacha, though for once it's Ki-tae doing all the drinking. He gripes at Jang-mi for learning nothing from her experience with Hoon-dong, and for not listening to him about Yeo-reum, while she sits in stony silence.
He's on a roll, and says that it's not that the guys she dates are bad, but that she makes them treat her badly. He goes on and on, listing everything she does wrong, not even noticing the giant tears rolling down Jang-mi's face. He's being so Ki-tae right now - everything he says is true, and it's even good advice, but he's not even attempting to say it in a way that's helpful or kind.
Finally she agrees that he's right, and he runs with it some more, telling her to be the bad one and demand better treatment from men. She should take what they offer and then throw them away first.
Jang-mi finally decides she's heard enough, and she declares that fine, she'll throw HIM away. Even though they aren't really dating, she's been doing the same thing with him that she does with other men, and she's going to stop. And he's the worst of them, because he knew he was using her, and she went along with it anyway.
Hoon-dong and Hyun-hee go out, and he spends the whole date whining about Jang-mi. Hyun-hee methodically refills his shot glass until he's completely wasted, and carries him home. She asks if it's okay that she's not a nice person and kisses him, and they spend the night together.
In the morning, Ki-tae panics when he gets a message from Se-ah that she's with his mother at the salon. She reassures him that she hasn't told his mother what she knows...yet. She warns that he'd better stop avoiding her calls, or she might just accidentally let it slip that his engagement is fake. She also mentions that later, they're going shopping at the department store where Jang-mi works.
At the store, it's obvious that Hyun-hee didn't get much sleep last night, but Jang-mi is hyper and works like a woman possessed. Hyun-hee says that she should slow down, since she'll be a VIP customer once she gets married, but Jang-mi says that it's not happening. Hyun-hee asks if Ki-tae found out that she kissed Yeo-reum, but Jang-mi just dodges the question and declares that she's done with both of them.
Yeo-reum shows up and asks Jang-mi to eat with him, but she's still angry and asks why she should. He just chirps with a cheery grin, "You said you like me!" She drags him out of the store to talk, barely missing Ki-tae, who's trying to find her before his mother and Se-ah can.
Jang-mi demands to know when Yeo-reum's lies started, and he doesn't deny taking money to get close to her, but he promises that he was giving it back. He says it was just a joke and that he doesn't like having to explain himself. Seriously, stop talking. You're making it worse.
His pretty smile isn't getting him out of this one, and Jang-mi tells him to leave her alone and pass the message along to Se-ah. But Se-ah and Ki-tae's mother overheard the last part of the conversation, and Mom demands to know what's going on.
