Ki-tae and Jang-mi stand in their wedding finery, at an altar under a stormy sky, both of them looking angry and hurt. Jang-mi says, "Let's fold." Ki-tae asks if this is what she really wants, with no regrets, and she stonily replies that it is. Ki-tae turns and walks away, leaving Jang-mi alone at the altar.
In the present, business is bustling again at "Ju Jang-mi" thanks to Ki-tae's mother's kimchi, and Jang-mi, Hyun-hee, and Yeo-reum are on top of the world. But Ki-tae has the unenviable job of bursting Jang-mi's bubble by telling her of her mother's breast cancer, and she listens in teary silence as she thinks to herself how life is full of surprises, and the worst always comes along with the best.
Jang-mi goes straight to her mother, who would rather talk about how she's hurt that Jang-mi didn't tell her she was dating Ki-tae for real. Jang-mi says that's not important and asks why Mom hasn't told Dad she's having surgery in two days. She thinks Dad will drop the divorce if he knows, but Mom says that's why he can't know - Dad will act sympathetic and come back, and she'll be stuck with him.
While they talk, Ki-tae accidentally finds the envelope of postcards from Dad and swipes them. Mom gripes at him for being a tattletale, tells him that she'll never accept him and Jang-mi, and kicks them both out. Ki-tae suggests they go see her father, since they now have his address.
As he drives Ki-tae tries to lighten the atmosphere, but he's thwarted by Jang-mi's bad mood at every turn. Finally he pulls over at a rest stop (also against her wishes) and orders lunch, saying he needs energy to endure her while she takes her upset out on him. He finally gets Jang-mi to eat by saying they can leave as soon as the food is gone. So cute.
Jang-mi asks why Ki-tae went to see her mom in the first place, and he says he was jealous that she was getting so much affection from his mother and he wanted the same from her mom. She's thankful that he did, since now her mom won't have to have surgery alone.
They find the little pond where Dad's been spending his days fishing, but he's not there. Ki-tae notices Jang-mi looks pale and she runs to throw up, but thankfully it's only from eating so much on a nervous stomach (and possibly also because Ki-tae just grabbed her and scared the crap out of her).
Ki-tae offers to take Jang-mi to the hospital, or the pharmacy, or to get married... Jang-mi's, "Stop it! Wait, what?" reaction is priceless. She accuses him of joking around to cheer her up, but he mutters that he wouldn't put his life on the line just for that. Jang-mi wants to wait until they're sure but Ki-tae is sure now, and Jang-mi gives him an epic side-eye.
She tells him it's not the right time because of everything her parents are going through, and commands him to take it back. But Ki-tae is sure her parents will make up, and even bets on it: If her parents get back together, Jang-mi has to marry him. I love his reasoning, that if the worst marriage she knows can work out, then surely theirs will too.
Jang-mi wants to know what was in her dad's postcards to make Ki-tae so sure (he previously told her it was the sweetest love letter he ever read, hee) and grabs them from him. He reclaims them and they adorably tickle-hug-wrestle for possession of the envelope. A passing fisherman picks up the envelope when Ki-tae drops it, and says he knows the man who wrote it, and that he was heading to Seoul today to close his chicken restaurant.
Having put the restaurant up for sale, Jang-mi's dad is pretty drunk on soju by the time they find him, and he roars at Ki-tae for having the nerve to show up here. Ki-tae stammers that he's dating Jang-mi, which enrages Dad even further, and he shoves Ki-tae against the wall yelling at him for hanging around his daughter but not intending to marry her.
Jang-mi's insistence that she's unsure about marriage just makes Dad even angrier and he demands to know what Ki-tae did to make her uncertain. When Jang-mi asks what Dad ever did to give Mom assurance, it takes all the fight right out of him, but the news that Mom has cancer hits him even harder.
