The episode begins after the kiss between Hae in and Hyun woo leaving the latter flustered. He follows Hae in as she enters the house worried about her turning the phone on. Hae in enters her room smiling to herself as she thinks Hyun woo is into her which is why he kept following her. While she’s in the shower, Hyun woo sneaks into her room and switches on her charging phone. He tries every password but nothing works until he tries a set of numbers. Hyun woo is shocked when the phone unlocks. He quickly proceeds to delete the message. However, Hae in catches him in her room. Once again, she thinks he’s interested in talking with her but Hyun woo manages to flee the room.
Hyun woo returns to his room but he becomes disheartened as he remembers the password to Hae in’s phone was actually the due date for their unborn child. After recieving news from the doctor that Hae in was pregnant, the two had prepared well for their baby but something bad must have happened. Now, Hyun woo’s current room is the room that would have been for their unborn child.
Hyun woo’s mother isn’t happy with how her children and husband are getting excited over recieving Hae In’s number. She’s also not to thrilled to the fact that Hyun woo is no longer divorcing Hae in.

The next day, Hyun woo watches as Hae in drinks orange juice to cure her hangover exactly what Eun Sung had predicted. Hyun gets a bit uncomfortable with it. Then Hae gets closer to him simply to brush off some dirt on his clothes and Hyun woo gets close to kissing her but immediately chastises himself after realizing what happened. Through out that day, Hyun woo is completely mesmerized in Hae In’s beauty, almost as if he’s seeing her for the first time. Even at the company, he can’t help admiring her changing expression as he stares at her through that window. He doesn’t understand what is going on with him. Eun Sung even gets scared and yells out when Hae in nearly trips as she’s climbing the stairs. Out of embarrassment, he hides in a shop but has to buy a pair of sneakers from the shop in other not to look weird.
Hyun woo ends up gifting the sneakers to Hae in which she wears around the store. Hyun woo later narrates how he’s been feeling to his friend and his friend quickly tells him he’s falling for Hae in but Hyun woo denies it saying he was only worried that her feet would swell due to the fact she’s always wearing heels.
Hae in and Eun Sung drive to meet Mr Hermann. He notices her sneakers and asks her about it and Hae in proudly replies it was from her husband. Eun Sung, slightly annoyed suggests she should have worn Hercyna heels but Hae in replies she was already doing a lot by wearing their clothes to the meeting. They arrive at the hotel to meet Mr Hermann. Eun Sung gives Hae in a tip about Mr Hermann’s Mistress to get him to agree to a deal with her. Hae in uses this to her advantage and Mr Hermann caves in. Hae in is happy and tells Eun Sung she owes him.
Hyun Woo buys peanut cakes to take home to Hae in causing his friend to believe that indeed he still loves Hae in. When she suddenly calls Hyun woo to tell him that she has something important to tell him, both get ahead of themselves thinking she wants to finally will all her properties to Hyun woo but that’s not it at all. At home, Hae in informs Hyun woo that she has finally found a research institute which has a fifty one percent chance of curing her. Hyun woo pretends to be fine with it but instead, it’s actually a nightmare as he imagines living in this hell of a marriage with Hae in for the next fifty years. He’s also thinks of how she’s bound to shoot him in the head if she discovers he ever wanted a divorce.
The next day, Bora interrupts chairman Man dae’s tennis date with Sun hee. She begs him to have a private dinner with her for her birthday. That morning, Hyun woo finds Eun Sung having breakfast with Hae in and is jealous of how close the two are. He recalls in the company when saw Eun Sung smoothening Hae In’s hair with his hand.

He even barges into their meeting creating an awkward atmosphere. Soo Cheol also barges into their meeting trying to win favor with Eun Sung.
Hyun woo relays his problem with his friend who advises him to let Eun Sung and Hae in fall in love. Besides, if he divorces her, Hae in can grant him alimony if she cheats but Hyun woo feels there’s something weird about Eun Sung. It can be anyone but not him.
Meanwhile, Grace poisons Seon hwa’s mind against Hae in saying that Hae in is the reason Eun Sung doesn’t want to invest in Soo Cheol’s business. She also lies that a shaman predicted she would always be an obstacle to her siblings. Seon hwa confronts Hae in accusing her of blocking her brother’s sucess but Hae In’s disease has set in, causing her to become so weak she can barely answer her mother. She nearly faints but Hyun woo sees her and holds her. He apologises to Seon hwa for the interruption claiming that Hae in wasn’t feeling well.
In their bedroom, Hyun woo urges Hae in to tell her family the truth. The fear that they would take her properties shouldn’t matter. However, Hae in reveals the real reason. She’s afraid that her parents would sink into despair since they already lost a child. Hyun woo can’t say anything to that.
Chairman Man dae rudely dismisses all his subordinates after a meeting. He then goes to have dinner with Bo Ra at a hotel but it was all a ploy by Bora for him to reconcile with his prodigal son. But Chairman Man dae is so angry because according to him, his son betrayed him by selling him out to prosecutors twenty years ago which made him to be jailed. He refuses the reconciliation and warns him to stay away from him and not even attend his burial when he dies. He then goes home to eat a meal prepared by sun hee. (I have a feeling she’s poisoning him)

The employee in the shop tries to calm them down but the man suddenly begins smashing all the other products in the shop.

To the delight of onlookers, they are dragged away by the security.
Meanwhile, Hyun woo’s father who is the village head is having a hard maintaining his position in the elections. His rival, park Seon hun is winning over the people. Even Hyun woo’s elder brother was won over with food and drinks much to his father’s dissapointment. At the debate between the two, Park Seon hun is more convincing where as the villagers mock Hyun woo’s father because even his daughter in law who is said to be the Queen heiress didn’t even bother to attend his birthday. They have no faith in him. But to everyone’s surprise, Hae in arrives in all her glory to the meeting introducing herself.
She brought truck loads full of gifts to the people and in front of everyone apologised to her father in law for not attending his birthday. This act alone turns the table and Hyun woo’s gains the people’s support again.
Turns out it was actually Hyun woo’s sister, Mi rae who texted Hae in to come and she did.

She sees a pink colored ipad in his drawer then goes outside to listen to the music playing inside there when a little boy sits next to her demanding to know who she is. When she tells him, he gets excited introducing himself as Hyun woo’s nephew Baek Ho yeol. He even requests a ride in her expensive car and Hae in agrees, instructing her driver to take him around the village.
The driver drives off with that child and as Hae in turns around, her sickness suddenly sets in and the pink ipad in her hand slips off. Hae suddenly finds herself in the middle of nowhere, her clothes smeared with mud. When Hae in realises herself, she breaks down in tears.

Hyun woo rides around the village in a bicycle until night when he finally sees Hae in the middle of the street looking disheveled. He yells at her out of fear demanding where she went but Hae in lies that she only took a stroll. She tells him to stop treating her like a patient. Hyun woo hurt, turns around to leave her but Hae in calls him back feeling bad when she noticed the sweat on his body and how dirty he was from searching for her. She then tells him she was scared when she found herself in an unknown place. This is actually the first time she shows her vulnerability since her diagnosis. Hyun woo feels for her. He rushes back and hugs her as tears roll down his eyes.
