At a lovely outdoor party, Ki-tae follows Jang-mi as she walks away from him, but she stops when he calls her name. They stand for a long moment, faltering every time they try to speak. Finally Ki-tae tells Jang-mi to go first, and braces himself expectantly for her words...
We go back to Ki-tae's hijacked proposal as Se-ah tells him that she told his mother all about the fake engagement. She says it was the only way to stop him, and says, "Let's turn back time." She asks why he didn't tell her three years ago why he wanted to be alone and hated marriage.
Ki-tae argues that she agreed that marriage was burdensome, but Se-ah says it was only to protect herself so that she could stay near him, if only as friends. She says he can tell her now and she'll comfort him, but Ki-tae just sighs in frustration. Se-ah tries one last time, and steps into the tea-candle heart with him, saying, "Let's get married."
Ki-tae just laughs scornfully, and says that things were good when there was distance between them. Se-ah says she has feelings too but Ki-tae counters that she can't just do whatever she wants. Se-ah finally breaks and cries that she told his mother because no matter what she did, all he thinks about is Jang-mi. Ki-tae whispers that he never wants to see her again, so she leaves, humiliated.
On the street, Jang-mi finally breaks free from Yeo-reum's hug to see Ki-tae's mother staring at them in horror. Mom whirls and walks away, and Jang-mi accuses Yeo-reum of doing that on purpose. He doesn't deny it and when she demands to know why, he simply says, "I like you."
Ki-tae calls Jang-mi, who just sadly apologizes for ruining everything. She blames herself for his mother finding out, but Ki-tae says it's not her fault and asks if they can talk in person. She says she can't face him now and they'll talk later, and Ki-tae runs out of his house. Jang-mi finds Dad at the restaurant and says she wants to talk to her parents about Ki-tae, but he says Mom went to her future in-laws' house. Yikes.
Jang-mi runs out on Dad mid-sentence, just before Ki-tae shows up looking for her. Dad can tell something is off and asks if they fought, and tells Ki-tae that her mom was heading to his house with a gift. Ki-tae quickly heads over there.
Jang-mi's mom delivers a wedding gift of blankets to Ki-tae's family, where Grandma and Aunt Mi-jung actually look pleased to see her. Ki-tae's mom comes to talk to her, the ice queen firmly back on her throne, and says she feels sorry for Jang-mi's mom.
Jang-mi arrives in time to be blasted herself, and her mom asks what she did wrong. Ki-tae's mom asks Jang-mi if she wants her to tell, or if she'd rather tell it herself. Jang-mi's mom is offended at being treated so badly when the wedding date is set, but Ki-tae's mother says there will be no wedding.
She announces that Ki-tae and Jang-mi's engagement was never real, that they faked it to make her give up on Ki-tae's getting married. Jang-mi's mom is shocked, thinking Ki-tae would never do something like that, and tells Jang-mi to set them straight. Wordlessly, Jang-mi only drops to her knees in apology and begins to cry.
Her mother finally accepts the truth and asks why, but before Jang-mi can speak, Grandma comes to her defense, and says that she knows it was an act but it was never malicious. Ki-tae's mom is upset to hear that Grandma knew, and says it must have been fun to watch her start to care for Jang-mi.
Grandma points out that Jang-mi always treated Ki-tae's mom well, but she's too upset to hear it, when she herself saw Jang-mi with another man. THIS is news to everyone, and Jang-mi's mom's legs give out as she asks if it's true Jang-mi has another man. Tears pour down Jang-mi's face and she can only say over and over, "I'm sorry. I'm so sorry."
Ki-tae's mom calls Jang-mi a pro at fooling people, which is one too many insults for her mother, and she grabs her daughter to leave. She carries the gift blankets with Jang-mi trailing behind her like a naughty child, until they run into Ki-tae. Mom screams at him for calling her "Mother," and tells him never to go near Jang-mi again. He tries to explain, but both women leave him standing in the street helpless.
