But Joo-Young thinks Hye-Na just got Ye-Seo out of anger. She tells Teacher Jo that Hye-Na knows how to provoke Ye-Seo, and he thinks they should thank Hye-Na because Ye-Seo replies them than before.
Joon-Sang complains that Joo-Young has already 20 minutes late, but she hasn’t called yet, and his mom even came to see her. But Madam Yoon thinks Joo-Young wants to be the one in power while she is the tutor, and all they need is Ye-Seo’s acceptance letter. Seo-Jin agrees Joo-Young is just a reference book she will use and throw away.
When Jin-Hee is watching the musical, she still recalls Hye-Na and Ye-Seo’s fight. Hye-Na falls off the castle and is dying. Ye-Bin screams when seeing Hye-Na lies on the ground with blood.
Joo-Young promises she will help Ye-Seo get accepted, Joon-Sang laughs because his mother will be able to achieve her dream of having three generations of doctors in their family. He thanks her. But Joo-Young tells him to thank his wife instead, and reveals Seo-Jin trusted her from the very beginning.
Seo-Jin smiles embarrassedly and gets a call from Ye-Bin. She goes out to pick up the phone. Ye-Bin says that Hye-Na fell off the balcony and is bleeding from her head. Seo-Jin asks Ye-Bin where she is. Woo-Joo is in the ambulance with Hye-Na, and tells Chi-Young that they’re headed to the ER. Joon-Sang rushes to outside, Seo-Jin is intention to tell him about Hye-Na. But he doesn’t hear it.
Hye-Na is sent to the hospital, and Chi-Young asks her if she is ok. She says that she wants water, Woo-Joo thinks she is thirsty. Chi-Young says he will give her some after the tests are done. Woo-Joo wants to follow Hye-Na, but a man gives a phone to him and guess it belongs to her. Chi-Young takes Woo-Joo’s hand and asks him what happened. Woo-Joo says that she went to the balcony after getting a text. Chi-Young checks Hye-Na’s CT and finds her epidural hematoma is quite big. So he asks the doctor to prepare her surgery fast.
Joon-Sang walks in and says they have a nine-year-old traffic accident victim. Joon-Sang finds out the child has same epidural hematoma to Hye-Na, so he wants to call his colleague. Joon-Sang guesses they’re drunk after the retirement ceremony, and asks Chi-Young to operate on the child first. But Chi-Young points out that Hye-Na lives in his house, and she is in bad shape. Joon-Sang claims the boy is the president’s grandson, and orders Chi-Young to save the boy first as the chief.
Hye-Na is sent out of operating room, and Woo-Joo the doctor why he didn’t operate. The doctor explains there was a more urgent case, and she will be transferred. Woo-Joo yells, “Where’s Hwang Chi-Young?” Hye-Na runs into Joon-Sang in the hallyway and calls him dad with her last voice, and is in tears. She wants to take his hand, but he asks the doctor to push her away. Woo-Joo asks Joon-Sang why he won’t help her when she arrived first. Joon-Sang claims there was a more serious case. Woo-Joo rushes to Hye-Na.
Joo-Young tells Ye-Seo over the phone that she did nothing wrong because it’s natural to hate and resent your rival. Woo-Joo tries to be close Hye-Na when she is pushed out of the ICU. But the doctor stops him because Hye-Na just died. Hye-Na’s phone drops from Woo-Joo’s pocket, Seo-Jin picks it up when he is very sad.
Seo-Jin thinks Ye-Seo killed Hye-Na and remembers Ye-Seo revealed her friend’s dad has another daughter her age, but her dad had no idea she existed, and she was the result of a mistake that happened before he married. Joon-Sang laughed and thought Ye-Seo’s friend is a nuisance, and she should’ve been prevented in the first place. So Ye-Seo asked Joon-Sang, “If someone shows up one day saying she’s his daughter, will you kick her out?” He said that it won’t happen because Ye-Seo and Ye-Bin will always be his only daughters. But Hye-Na blamed Joon-Sang for calling the girl a nuisance since she is a child.
Seo-Jin keeps calling Ye-Seo when returning home, and finds her in bed. She yells, “Who were you on the phone with? You ignored all my calls.” Ye-Seo says it was Joo-Young. Seo-Jin asks Ye-Seo what happened to Hye-Na, and lowers her voice, “You were at the guest house too.” Ye-Seo says that she was listening to a lecture with her earphones on in the master room, so she didn’t even know Hye-Na’s falling. Seo-Jin asks Ye-Seo that who saw her listening to the lecture, and reveals Hye-Na is dead. She thinks they two were enemies, and if people find out that they two are half-sisters, the police will suspect her first. She mentions she provoked her even this morning.
Ye-Seo reveals Hye-Na threatened to post about her being Joon-Sang’s child on the school website. Seo-Jin guesses they fought. Ye-Seo yells, “Do you think I killed Hye-Na?” Seo-Jin warns Ye-Seo not to tell what she just said to anybody else. Ye-Bin walks in and thinks Hye-Na will be okay after the surgery. But Seo-Jin reveals she went to a good place. Ye-Bin is on her knees and cries out.
Seo-Jin sneaks into Hye-Na’s basement with gloves. She tears up the family photo of Hye-Na’s mom and Joon-Sang, and breaks Hye-Na’s phone with a hammer. She steps out and chases the garbage truck, throwing Hye-Na’s stuff into the garbage truck.
Jin-Hee thinks something must be happened between the two girls, Yang-Woo asks his wife to keep her lips sealed. Chi-Young runs into Woo-Joo in the house before he goes to school. He says that he had no choice, and feels sorry. But Woo-Joo says, “Mom told you her stomach was upset, but you gave her digestive pills and went to some hospital to volunteer.” He thinks Chi-Young killed Hye-Na, and breaks the flower pot with his bag. Ye-Seo sees Woo-Joo walking alone at street, and keeps staring at him. Teacher Jo notices it.
Ye-Seo steps in the classroom, the students think she killed Hye-Na. Seo-Joon tries to contact Woo-Joo, but he doesn’t pick up. He asks his brother if Woo-Joo will be okay. Ki-Joon doesn’t think so and reveals he is barely staying sane himself. Ki-Joon notices Ye-Seo stays strong-minded, and thinks she killed Hye-Na. But Seo-Joon disagrees, “Ye-Seo can be selfish, but she’d never do something like that.” Ki-Joon points out that they were always fighting because of their grades, they practically hated each other. Ye-Seo glances at Ki-Joon.
Seung-Hye grumbles, “That girl who didn’t even have a mom and lived so poorly,” When Se-Ri is eating soup. But Min-Hyuk rushes in and yells, “You guys fought?” He startles the mother and daughter. Seung-Hye offers to talk after Se-Ri finishes her meal, but Min-Hyuk is in panic because everyone saw they fight. Se-Ri places down the spoon, and claims they quickly made up. But Min-Hyuk points out that the police won’t believe the girl who drinks and dances in clubs. Seung-Hye explains Se Ri works as a club merchandiser, and she is a professional.
Se-Ri leaves table with temper, Min-Hyuk follows her and questions, “Why did you made cocktail and go to the party since you did nothing right?” But she ignores him. So he persuades Seung-Hye to make their daughter go to university. But she says Se-Ri doesn’t want to go to there because she enjoys what she does. But he asks her, “Would you trust a kid that gets the highest grades in her year, or would you trust a fraud that lied that she’s a Harvard student?”
The police visits Hye-Na’s room, and he heard Ye-Seo and Hye-Na used to be rivals. Seo-Jin explains that she won’t keep her if the girls were on bad terms. He asks what kind of student was Hye-Na. She says the girl is smart, polite, and diligent. Another police asks if she had a laptop. She is surprised and denies then. The polices want to see the girls who were at the guest house last night.
The police doesn’t think it’s an accident when he talks with Joon-Sang’s family. He asks the girls what they did when someone called 911. Seo-Jin explains for her daughters, and asks the police to check the CCTV. But the police claims there isn’t any CCTV inside the castle, and asks to check Ye-Seo’s laptop if she were listening to the online lecture. Seo-Jin hints Ye-Bin to speak out Se-Ri and Hye-Na had a fight while playing Mafia.
During the mafia game, Se-Ri thinks Hye-Na is a mafia because she spread her rumors. Hye-Na thinks Se-Ri is a mafia as well, since she lives such a pathetic life. Se-Ri smirks because she thinks Hye-Na is inferiority. Hye-Na points out that her mom loved her for who she is, but Se-Ri’s father just treats her as trophies. She thinks Se-Ri is like the mafia who don’t stop at anything, even family. Because she backstabbed her father.
The police thinks Se-Ri killed Hye-Na because she told others that Se-Ri wasn’t a university student. But Seung-Hye points out that Se-Ri wasn’t the only person Hye-Na fought. The police asks Woo-Joo why he went to the balcony, Woo-Joo lifts his head and says that Hye-Na texted him. So the police asks to check his phone.
The families gather to take about Hye-Na’s case, but they suspect each other’s kids. They fight with each other after Min-Hyuk made Joon-Sang’s nose bleed. They stop when Soo-Im drops the pillow on the floor. She is sad because people don’t care Hye-Na when she is dead. Chi-Young takes his wife away because the adults don’t act like adults.
Jin-Hee looks at Joon-Sang with anger when he cares his nose, and shares Ye-Seo and Hye-Na had a fight. So Seung-Hye stares at Seo-Jin with anger. Jin-Hee returns home and complains that Joon-Sang blamed other kids since he has an illegitimate kid. Yang-Woo explains Joon-Sang doesn’t know Hye-Na is his child. She is furious to disclose Hye-Na’s origin, but Yang-Woo stops her.
Seo-Jin remembers Jin-Hee said Ye-Seo and Hye-Na had a fight, and realizes she knew it. So she visits her when Jin-Hee is going to sleep. Seo-Jin is on her knees when Jin-Hee doesn’t accept Seo-Jin’s apology. So Jin-Hee has to let her in. Seo-Jin shares Joon-Sang doesn’t know Hye-Na is his daughter. Jin-Hee is shocked and thinks she would’ve grabbed her husband by the collar and tortured him. Seo-Jin regrets that Hye-Na died before she could even call him Dad once.
She grasps Jin-Hee’s hands and apologizes for hurting her feelings. Jin-Hee admits that she kept provoking Seo-Jin intentionally.
Min-Hyuk is tired, so he gets a cup of coffee himself while touching the wound on his face. Se-Ri returns home and dresses sexy. He yells at her, “If you were actually a Harvard student, no one would dare to suspect you.” Seung-Hye suggests to talk it later since Se-Ri worked all night and just got home. But he says that everone said Se-Ri is the most problematic one in the Castle. Se-Ri turns around and tells her father not to use others as an excuse because it’s what he thinks. She says that she was in the kitchen after the mafia game, then Hye-Na called her, so she stepped out.
Hye-Na apologized to Se-Ri when they were at balcony, “Se Ri, I was out of line earlier. I’m sorry. I should’ve been more thoughtful.” Se-Ri said, “I envy you for being proud of your mom. I know she passed away, but you could stay strong because of her. I’m sorry I talked about insecurities and provoked you.” She smirks, “I was the mafia. Wait and see. I’ll show you how the mafia can turn her life around.” She handed out, so they shaked hands.

We return the scene of the father and daughter’s fight. Se-Ri says, “You jumped to the conclusion that no one would believe me because I had lied about going to Harvard. Just because you think so.” Min-Hyuk agrees, “This is precisely why you have to go to college.” She smirks, “Why do I have to go to college? My dream is to work hard so that I can open a club with my hard-earned money. Must I really go to college? I didn’t actually get accepted to Harvard, but I have experienced everything. I thought the best university in the world would be very special, but it was no big deal. All those students are human too. I’ve seen people who got accepted because they hired someone to take the SAT. They all lie and cheat. I’ve even heard some say that not cheating in exams means you don’t want to be number one. It’s not like every Harvard graduate is successful. A guy I know is in a mess because his life went downhill even after he graduated from Harvard.”
Min-Hyuk thinks it’s just a rare case, “If you’re a Harvard graduate, everyone…” Se-Ri says, “They acknowledge you? Who cares whether they acknowledge you or not? I just want to be happy. Dancing gives me joy. I get so excited when I see people relieving their stress at the club.”
Se-Ri thinks her father only respects those people who graduated from elite schools, and leaves. Min-Hyuk sighs because he just talks with a wall.
Ye-Seo is sleeping on the desk and apologizes to Hye-Na in her dream. But she wakes up when getting a call. Seo-Jin is cleaning Hye-Na’s room, but the maid rushes in and takes the cleaner from her. Seo-Jin sees Ye-Seo rushes out, so she chases her. But she sees her daughter walking in Joo-Young’s arms, and Joo-Young takes Ye-Seo away.
When Ye-Seo falls asleep, Joo-Young texts Seo-Jin that her daughter will stay with her tonight. Seo-Jin suspects the two killed Hye-Na. Because Ye-Seo was talking with Joo-Young when Hye-Na died. So she asks Joo-Young about it, Joo-Young plays the recording that Ye-Seo wanted to kill Hye-Na. Joo-Young says that they need find a scapegoat. So the police arrests Woo-Joo.
