As we revisit all of Jang-mi's emotional, violent, embarrassing outbursts with beer, dried fish, and other sundry goods in hand, she narrates that she really did not want to be that girl in front of "that person" anymore.
But as she's saying it, she approaches Ki-tae and his mother ominously with a pitcher full of makgulli. They shrink back in terror and scream "Noooooooooo!" in slow motion, but she throws the makgulli right at them, and then laughs maniacally.
Rewind to the morning after the sleepover, when Jang-mi comes rustling out of the bedroom in nothing but a T-shirt to find Ki-tae's mom standing in the living room in shock, surrounded by underwear strewn about-undeniable evidence that this was not an innocent playdate.
To make matters worse, Ki-tae comes out only half-dressed in a robe. Mom just spins on her heels and walks out without a word. As soon as she goes, they scramble to put some clothes back on, nearly trading underpants in the process.
They race out to catch Mom before she gets in the car, and she points out how many unbelievable incidents she's had to swallow since she met Jang-mi: Ki-tae bringing her home as his fiancée to wreak havoc, finally accepting her only to find that it was all a lie, and now seeing them together after promising not to hurt each other again.
Mom asks how she's supposed to accept this, asking incredulously if they really mean to try and marry after the epic fiasco between their families. But Ki-tae jumps in to say that they aren't going to be married-they're only going to date. Hearing it come out of Ki-tae's mouth like that seems to shake Jang-mi, and Mom scoffs even harder, if that's possible.
Later at the bar, Jang-mi confesses that she didn't like hearing Ki-tae tell Mom that, even though it was really her idea not to marry him. Hyun-hee guesses that she does want to marry, while Yeo-reum thinks it's more about being accepted by Mom as Ki-tae's equal.
Hyun-hee calls that a pipedream and asks how two women who love one man can ever get along. Did she just sum up all mothers and daughters-in-law in one pithy statement? I'm sure it's more complicated, but that sounds about right.
Ki-tae goes home to calmly explain to Mom that he's sincere about Jang-mi and this isn't some attempt to rebel. Mom doesn't believe that Jang-mi is sincere about him though, and accuses her of working with Yeo-reum because she plans to live her life like Ki-tae's father-love and needs met in two separate people. Ouch.
Ki-tae defends her, but Mom isn't convinced. Jang-mi calls on his way out, concerned that they ought to go see Mom and explain things, but he just tells her not to worry about it.
Back in the house, Grandma thinks all of this is a good sign that Ki-tae is maturing, but Mom says the kids don't plan to get married. Grandma catches on that what Mom is really upset about is that Jang-mi didn't come with Ki-tae, and suggests a plan to find out what Jang-mi's true feelings are. Mom seems intrigued.
Over at Jang-mi's house, her mother continues to get one-word postcards from Dad and sighs. She still thinks Jang-mi is frying chicken all day, and finally hears that she opened a restaurant with her friends. Mom laments that she spent her entire life to get away from selling alcohol, and Jang-mi's doing it voluntarily.
She argues that there's nothing wrong with selling liquor at a restaurant and doesn't see what's so bad about people having a drink after a long day, but Mom only sees her own unhappiness, and tells Jang-mi that she can be their witness in court that her marriage was a failure.
Jang-mi is distracted all day at work, and the team sighs that business has slowed severely after their grand opening. Yeo-reum says it's because their kimchi pancakes aren't up to snuff, and asks Jang-mi where that kimchi came from that first time he made them back at Hoon-dong's place. She cringes-that's Ki-tae's mom's kimchi.
