At Yi-Jun’s house, Jae-Hee kicks Yi-Jun away in Love in Disguise episode 4. The chandelier falls. Jae-Hee is hit by the chandelier. Yi-Jun asks Jae-Hee is she fine? But she worries about him. Myung-Suk shows up. She asks the two what happened. Yi-Jun asks Myung-Suk to go to take first aid kit. He calls the dean. He wants to take Jae-Hee to the hospital. But she says she’s not serious, and she doesn’t need to go to hospital.
Yi-Jun grabs Jae-Hee’s wound. He asks her is it not serious? He tells the dean that he will arrive at the hospital within ten minutes. His personal secretary was seriously injured. Jae-Hee takes over the phone from Yi-Jun. She tells the dean that she’s fine. She hangs up.
Yi-Jun asks Jae-Hee what is she doing? She says she didn’t break any bones. Myung-Suk comes back with the first aid kit. Jae-Hee takes the kit. She says first aid kit is enough. She walks away.
Jae-Hee gets in the bathroom. She remembers the chandelier fell. She wonders why did the big thing fall? Yi-Jun reaches the bathroom. He asks Jae-Hee to open the door. She doesn’t understand why he’s so angry. He remembers he opened the door, and his mother died. He gets the key from Myung-Suk. He opens the door.
Jae-Hee gets dressed. She tells Yi-Jun that he should worry about himself. If he didn’t step aside, he would die. She mentions he asked her to be careful. She asks him did he mean it? She shows him the wound on her arm. She claims that she just has a scratch on her arm. Who would go to see a doctor for a little injury like this? The family is happening something that she doesn’t know. She asks him what it is.
He dresses her wound on her forehead. He thinks she lied that she served in the Special Forces. She reminds him that she saved him. She figures he doesn’t need her anymore. He fires her, and he asks her to get lost. Si-Hyun breaks into the bathroom. He asks Yi-Jun what does it mean he was saved? He wants to report it to the chairman. Yi-Jun points out that Chairman expected it, or he has known it. Si-Hyun is surprised that Chairman knew it, and he tacitly approved.
Yi-Jun says he’s not the only one who knows his father’s style. Everyone grew up while they witnessed it. His father only accepts the winner. Si-Hyun asks Yi-Jun does he know who did it?
Bong-Yi calls Jae-Hee. He says Team Leader Park disappeared. But there’s another person tracking him down, except them. Bong-Yi thinks the chandelier didn’t fall on its own. Yi-Jun expected it.
Yi-Jun tells Si-Hyun that nobody is suitable than Jae-Hee. He wants to take back the order that he fires her. He finds an excuse from the laws. But Si-Hyun tells Yi-Jun that it doesn’t apply to him and Jae-Hee. Because they didn’t sign like that. Yi-Jun asks Si-Hyun to find a way.
Jae-Hee takes a photo of the chandelier. Si-Hyun and Yi-Jun walk out of the study. Si-Hyun runs to Jae-Hee. He thinks there will be aftereffects. He persuades her to go to see a doctor. He mentions the law. She says she doesn’t hold it against Yi-Jun. If she feels wronged, she can contact him anytime. She’s the life saver of Yi-Jun. He wants to help her seek the maximum compensation. He tells Yi-Jun that he cannot fire Jae-Hee.
Yi-Jun asks Si-Hyun to leave. Jae-Hee stops Si-Hyun. She asks him is it true that Yi-Jun cannot fire her? He says yes. She tells Yi-Jun that she found out that she was seriously injured. He takes her into his room. She says it was very hard to save him. She asks him to recognize her contributions. But he points out that it’s her job. He knows she saw it all in the room on the second floor.
It flashes back. Jae-Hee finds the phone in the room. But there’re only cat photos on the phone. It’s not Eun-Young’s phone. She sees a sword that is hung above her head.
At present, Jae-Hee explains it to Yi-Jun that she just got in and took a look. He learns that she saw it. He knew it would happen. He blames her for wanting to flee after she saw it. He wants to know how she will spread the rumor about him. She talks back that he fired her first. He tells her that it’s cancelled that she’s fired. She wants to know what happened. But he refuses to leak it. She says since she’s going to continue to come to work, she cannot pretend she doesn’t know it. She needs to be on guard.
He tells her that she will hate him if she keeps doing it. She asks him doesn’t he trust her? He asks her not to care for anything that she shouldn’t care for. She just stopped a crystal chandelier. She didn’t achieve a great feat. If she wants to take money, she just needs to complete the tasks that he gives her.
In the evening, someone tails Hye-Jung home. She takes out her Pepper Spray. She uses it to attack Si-Hyun. She realizes that she misunderstood him after she saw a guy leaving.
Si-Hyun washes his face in Hye-Jung’s bathroom. She hands over a glass of water to him. He drinks up the water. She apologizes to him. She didn’t know it was him. He says he has feelings for her after she apologized to him with the expression. He asks her did someone tail her? She mentions they have a meeting tomorrow. He explains it to her that he left something here. She knows he intended to use the tie. He thinks she’s very perceptive.
She drives him out of her house. He holds his tie. He asks her does she want him to leave like that? She says she doesn’t like the man who comes after the appointment was cancelled. He knows she’s interest in his appointment. She wants to know if Yi-Jun is going to take over the company. This is why she asked him out. He tells her that he came not because the appointment was cancelled. Because he missed her. He offers to have dinner together next time. He lets her decide it.
At the police station, Seok-Jin is told that the chain of the crystal chandelier was cut off by someone. At Yi-Jun’s house, Yi-Jun remembers Jae-Hee kicked away the couch. He kicks the couch, but his foot is hurt. In the evening, Jae-Hee gets off the bus. It’s raining. Seok-Jin holds umbrella for her. She’s happy after she saw him. But she asks him what is he doing here? He tells her that everyone is waiting for her. He came to pick her up after he lost the rock-paper-scissors game.
She remembers there’re a lot of umbrella in the office. But he only took one. He says he didn’t see it. He heard that she was almost hit. He asks her to take care of herself next time. She says she wanted to save the guy so that her body reacted first. Because he’s a suspect who’s under investigation. This is a kind of occupational disease.
Seok-Jin tells Jae-Hee that she couldn’t look into the suspect if she was hurt. It’s very important to build trust relationship. But she shouldn’t let her emotions get in the way.
At the cafe, Jae-Hee recognizes Na-Jung from the footage. Wan-Gu realizes that Na-Jung was the one who provided them with intelligence. He thinks an evil person should have protected her family and her brother. Bong-Yi wonders why Eun-Young’s case was exposed when Yi-Jun is going to take over the company. Seok-Jin thinks it’s the fight of the rich family. Bong-Yi admits that Na-Jung benefits the most when Yi-Jun is treated as a suspect.
In Na-Jung’s office, Na-Jung reads the contract. She learns that Chairman loves his son very much. She throws away the contract. She asks Si-Hyun not to provoke her. Once she’s going crazy, she cannot control herself.
At the cafe, Seok-Jin gets a call from the forensic pathologist. He tells Bong-Yi that herbicide components were detected in the milk. Bong-Yi mentions the phone Jae-Hee found in the room doesn’t belong to Eun-Young. Wan-Gu thinks Yi-Jun was weird. Why didn’t he let Jae-Hee get in the room? There’s nothing important in the room. Jae-Hee says the room is a hobby room. Everyone has his personal life.
But Jae-Hee’s team members get the wrong idea after they heard her words. She tells them that she was caught to take back the glasses. But Wan-Gu believes that she had fun in the room. She tells him that he has a vivid imagination as long as he’s at a time like this. He just crossed the line.
She watches the footage again. She realizes that Yi-Jun doesn’t threaten Eun-Young. He stops her because he worries that she will be in danger because of him. He said something like that to Jae-Hee. Seok-Jin asks Jae-Hee does she want to clear Yi-Jun of suspicion. She denies it. She’s just speculating. It makes sense if they exclude Yi-Jun.
The next day at Yi-Jun’s house, Jae-Hee asks Myung-Suk why did Si-Hyun prepare the milk? Myung-Suk explains that it’s imported milk. There’s an imported food store near Si-Hyun’s house.
Jae-Hee tells Yi-Jun that she worries about him. Because he didn’t call her. She takes him to the park to be sunbathing. She says Vitamin D is very important to the person like him who stays cooped up at home all day. He’s the Cocooner who lacks social skills. She teaches him to work out. But he wants to do it on his own. She protects him when the two kids ride their bikes past. She tells him that the situation was very dangerous at the time.
The kid throws the ball at Yi-Jun. Jae-Hee catches the ball. He asks her not to overreact. She sits on the bench with him. He asks her why was she overprotective of him? He thinks she’s inexplicable warmth. He mentions she treated him as her enemy. She asks him does he lose his mind before he didn’t sleep? He was very slow when the chandelier fell. She has to be overprotective of him.
He thinks she’s way too out of line. But he agrees with what she said. She asks him how did he get to know Si-Hyun so well? He asks her why is she interested in the guy suddenly?
In Chairman’s office, Si-Hyun reports to Chairman that he prepared the succession process. Chairman asks Hye-Jung to make sure that Yi-Jun is going to attend the meeting. She says she will confirm it through the Secretary’s Office.
Si-Hyun and Hye-Jung leave Chairman’s office. He asks her did she decide to have dinner with him? She tells him that it depends on him. Na-Jung tells Chairman that Min-Hwan was the only one who witnessed who killed Eun-Young. But he disappeared. Na-Jung asks Chairman does he want to know what Yi-Jun did behind his back? She reminds him that he doesn’t have just one child.
At Yi-Jun’s house, Yi-Jun refuses to attend the meeting. Jae-Hee says she will be scolded if he does so. She tells him that it’s Chairman’s order. He says his father didn’t tell it to him. He drives her out of his room.
Outside, she regrets for saving him. She calls Hye-Jung. She tells her that Yi-Jun won’t attend. She asks her why does Yi-Jun have to attend? Hye-Jung says Chairman will appoint a successor. Everyone will attend.
Jae-Hee returns to Yi-Jun’s room. Yi-Jun asks her why didn’t she knock at the door? She asks him to take a chance on her. If he loses, he goes to attend the meeting. He refuses to make a bet with her. She tells him that she won’t report the falling of the crystal chandelier if he wins. As his personal secretary, she should report it.
He tells her that he’s her boss. But she shakes her head. She says she’s affiliated with Taekang secretary team. Chairman will know it through the director of Secretary Office. He asks her is she threatening him? She says she’s asking him to cooperate. Recently, a series of strange incidents have been happening around him. But he doesn’t call the police, and he doesn’t tell it to his family. Once Chairman hears it, things will get complicated. If he doesn’t attend, Secretary Team will hold her accountable. She has to tell the truth.
Yi-Jun and Jae-Hee have an arm-wrestling match. He thinks she’s so despicable. She says she tried her best to be mindful of fairness. She asks him does he want to change a game? He can choose boxing. He says he eats Wild Mountain Ginseng each year. If he wins, she won’t mention party in front of him. Her hand is very small.
Jae-Hee wins after she blew a kiss at Yi-Jun. She’s excited to hug the judge Myung-Suk. Yi-Jun blames Jae-Hee for committing a foul. But she says she learned it from him.
In the evening, Chairman is waiting for Yi-Jun at home. Man-Suk persuades Chairman not to give the company to Yi-Jun. He thinks the kid isn’t ready for it. But Chairman thinks Yi-Jun should be eliminated if he cannot take the duty.
Mi-Jin picks up her daughter Ka-On. Ka-On doesn’t want to go to the party. She’s not free to attend her uncle’s Coronation Ceremony. Because she’s a senior in high school. Mi-Jin reminds her daughter that she’s close to Yi-Jun. Ka-On says this is why she goes to the party. She believes that he will give a subsidiary to her. Mi-Jin laughs. She thinks Ka-On is way too ambitious.
Yi-Jun arrives at the family banquet. He bows to Chairman. Jae-Hee runs into Na-Jung. Na-Jung wonders why did Yi-Jun choose Jae-Hee? She thinks she can get to know her little by little later. She asks her how much does she want? She wants her brother’s intelligence. Jae-Hee realizes that Na-Jung approached people around Yi-Jun. She asks her not to expect it. It won’t happen. She asks her did she do the same thing to Eun-Young? Na-Jung tells Jae-Hee that she should follow the right person. Jae-Hee says she will decide which side she chooses.
At the banquet, Joon-Hyun heard that Yi-Jun was sick. He invites him to go to Fiji with him. Yi-Jun says his illness isn’t serious. He doesn’t need convalescence. Chairman tears up the contract. He refuses to give the company to Yi-Jun. Because Yi-Jun got himself into trouble. Chairman tells the people that everyone will have a chance. He will announce the successor in the next shareholders’ meeting.
After the dinner, Na-Jung asks Yi-Jun why didn’t he perform well? He didn’t eat it when the food was right to his mouth. He says he drank the poison. Na-Jung mentions she told Jae-Hee to choose the right person. Her master has lost power. She misjudged the situation.
In the car, Jae-Hee asks Yi-Jun does he need some comfort? Although she’s not good at comforting people, she will try her best. She tells him that something good will happen to him since he got a bad luck. He asks her to focus on her driving. He expected it early. He’s surprised that she was loyal. She tells him that she wants to take his side.
Outside the bar, Hye-Jung calls Si-Hyun. But he doesn’t pick up her phone. So she leaves the bar. At Yi-Jun’s house, Jae-Hee tells Yi-Jun that she gets off work. He invites her to have a drink with him. She rejects it. But she says she can listen to him vent. She can accompany him to drink. But he needs to answer her a question.
At the restaurant, Na-Jung drinks with Si-Hyun. She tells him that a dog cannot choose his master. The master is the one who’s choosing the dogs. She asks him to make it clear who’s his master. He says he’s not a dog. Taekang is his master. She asks him where is Min-Hwan?
At Yi-Jun’s house, Jae-Hee is drunk. Yi-Jun takes her to his Collection Room. She points at the doll. He reveals it’s the last present that his mother gave him.
It flashes back. His mother tells him that Yala will protect him all her life. It was made by her. At present, Jae-Hee finds out that all the heroes are in the room. She figures Yi-Jun wanted to be a hero. He says he wanted to protect them. But he didn’t protect anyone in the end. She tells him that his biggest problem is his personality. His personality makes people want to drink. It’s hard to make decision to protect someone.
He mentions he didn’t protect anyone. She points out that he protected her. He worried that she would be in danger after she knew what happened. So he was mean to her. He did the same thing to Eun-Young. He said those words to blame himself at the cemetery. She knows he let her mistake him for a bad boss. Eun-Young and his mother knew it as well.
Yi-Jun cries to ask Jae-Hee why does she always see though the thoughts that he doesn’t want anyone to know? She asks him doesn’t he kill Eun-Young? He says yes. She feels relieved after knowing the answer. She leans on his should, and she falls asleep. Jelly wakes her up. Jae-Hee chases Jelly out of the house. She tries to catch her. But Yi-Jun holds Jae-Hee. He releases her. She falls on the ground. She rushes toward him, and she grabs his collar. They fall on the ground together. She kisses him.
