Episode 94
Professor Song debuts on the Healing Garden show along with returning co-host Seonghyun Moon. Song was initially annoyed that Moon only approached her on television, but decided to go on the show anyhow. She explains on the show that fear is a major problem that the youth are facing, and it can lead to paranoia. She then goes on to explain one patient she dealt with who had paranoia. Seonga is excited to hear about Moon, since he is famous on social media. Professor Song gets an email from someone asking if she remembers them, and she replies asking who this person is.

When Song returns to her office, the she picks up a letter addressed to her. It states that she is no counselor, that she ruined their life and that they are going to kill her.

Episode 95
Professor Song tells her colleagues about the letter and they urge her to go to the police, but she does not want to share her patient's information unnecessarily. She continues to recieve letters from the sender, this latest one saying that she made them seem crazy on television. Professor Frost says that the sender seems impulsive, and that it must have had something to do with the Healing Garden show. Professor Song calls Moon and asks if he is alright, since he was also on the show. He replies that he is fine, and looks concerned.

Episode 96
Professor Song asks Professor Chun to have tea in her office, and they discover that her office was raided and destroyed. Professor Frost calls the police. When they arrive, the detectives and Frost say that the burglar must have been an amateur because they opened the drawers in a haphazard fashion. Seonga asks how Frost knew this as well and he says he worked for the police briefly. Professor Oh tells Seonga not to mention it, because Professor Chun does not like that portion of Frost's past. Moon recieves a call from someone and smiles, telling them to keep him posted.

Episode 97
Seonga asks Professor Oh to clarify about the police incident. He tells her that a long time ago, Frost was chosen along with other psychologists to work as profilers for the police, although Frost only worked unofficially for them. He is not sure why Chun disapproved of Frost, since he recommended others before.

Professor Song is struggling to hand over the papers, and she asks Frost what she should do. He tells her that it is her choice, but he suspects that she feels guilty about not helping her patient. She asks what she should do if it really is her fault that a patient's life was ruined. Professor Frost remembers Seol and tells Song that she should consider whether the problem is truly her fault or not. Then he mentions that the culprit likely stole their file, so they should cmpare the physical record to the digital record to find the missing one.

Seonga is walking with Pavlov when he starts barking suddenly. She asks what the problem is. Behind a wall, a shadowy figure stands still.

Episode 98
Song and Frost sift through the files of her earlier patients. Professor Song is still worried that she might be to blame, and she wonders if Frost felt this guilty about the outcome of her sister's case. Professor Frost announces that the number of cases are the same, and nothing was stolen. Song wonders if the patient is male due to their strength of opening the cabinet, but Frost discounts that with the possibility of a tool. He starts listing and crossing off possible mental illnesses in an attempt to narrow down the patient. Seonga and Professor Oh invite them to lunch, but are stuck working with Song and Frost. Professor Chun comes in but leaves when he sees the serious atmosphere.

Professor Song and Frost have narrowed down the list of patients with symptoms of paranoia. Frost asks Song if she would like to meet her patients.

Episode 99
Professor Song is uncomfortable with the thought of meeting her former patients. Professor Oh and Frost brought a remote alarm and button for her to install under her desk, in case she is in danger. Professor Frost is surprised that she is still accepting patients in this dangerous situation, and she says that she has to keep moving. Outside her window, a strange man observes her.

Professor Frost notices mail in Song's inbox, and picks it up. The letter says that it looks like Song still doesn't remember them. Frost remembers that Song spent some time away from the university, so her patient must have been transferred to someone else. Their files would most likely be with Professor Chun. Professor Song welcomes her patient Seongjin Kim.

Episode 100
Professor Frost races through the old files and finds one belonging to a font designer. He recognizes the letter sender as Seonggyeom Kim, one of Song's former patients. He sees a man staring at Professor Song's window and runs outside to find him. He asks the man who he is and he turns away. The professor tries to grab him but the man flips him onto the ground and continues to leave.

Episode 101
Seonggyeom tells Professor Song that he works as a font designer, but he feels like everyone hates him. Ever since he was young he's felt this way. Then he met someone who treated him like a person, but then he realized that she secretly thought of him as a lunatic. Seonggyeom reaches into his pocket and Song reaches for her button, but she brings her hand back.

Professor Song tells Seonggyeom that she recently recieved letters from a friend and a patient who was hurt by her. She used to have a sister who suffered from a mental illness, and she eventually succumbed to it. She trusted her friend to help that patient, and resented them for a decade for not being able to do so. Recently, she learned that she was also able to hurt her patient. She was 24 at the time, and has met many patients since then, but she never thought of Seonggyeom as a worthless person. She tells him that she is glad that he came.

Professor Frost chases the strange man to find him standing with Moon. Moon takes out an earpiece and applaudes Song for being able to remember her former patients. He tells Frost that the man is his assistant he sent to keep an eye on Song, and Frost asks if he really meant to help her. Moon says he is not there to help Song, but to take her with him.
