Episode 89
A group of girls observe Dr. Frost reading his books spread out on the library table all at once. He asks them what book one of them is holding, and sees it belongs to Seonghyun Moon. The professor remembers their meeting 19 years ago at the Yonggang library.

Nambong still had the habit of reading his books spread out at once. The librarian scolded him about it, and he walked away from her. When he returned with Professor Chun the latter apologized for Nambong's habits. He told the librarian she doesn't have to clean up after Nambong since he would remember the position of the books.

Professor Chun asks Nambong if he would like to bring the books to the lab. Nambong asks Professor Chun why he controls his expressions so carefully but other people do not. Chun tells him that Nambong should take it slow when reading people's expressions. He then asks Nambong if he thought about his offer before to study psychology.

Episode 90
Nambong returns to the library and notices that one person has been reading all of his books: Seonghyun Moon. He tries to guess which book Moon will read next.

A person comes and picks up Nambong's book that he set down. He goes outside to read it on a bench, and some students approach him. They tell him he has a clear energy, and they say they have studied the truth about people. The man smiles and asks if they would like to know about people.

Episode 91
Nambong picks up a book at the same time as the man. The man apologizes and says that he needs the book, and Nambong walks off. He asks the libarian who the kid is, and she tells him that the boy is Professor Chun's son. The man sits down with Nambong and he notices the name on his ID is Seonghyun Moon. He tells Nambong he is reading some interesting books.

Nambong and Seonghyun sit outside of the libary. Seonghyun tells Nambong that his hair is interesting, and Nambong starts saying he is not an albino. Seonghyun says that he knows Nambong is not albino, and that is must be tiresome having to explain it all the time. He asks why Nambong reads his books in that manner, and Nambong explains that he reads them in that manner to find the connection between them. Nambong then describes the author of Seonghyun's book Dennis Morris, and his career as a psychologist. Seonghyun wonders if Nambong has autism. He asks Nambong if he knows about humans before reassuring him that nobody truly does. Nambong asks if he knows the answer, and Seonghyun says that it would have been better if he didn't.

Episode 92
Nambong and Seonghyun continue to bond, and Professor Chun recognizes Seonghyun as one of the new freshmen. He asks Seonghyun if he would like to work as an assistant in the counseling center. He also thanks Seonghyun for spending time with Nambong, saying that Nambong needed a friend. Seonghyun says that the pleasure is his, and he didn't have many friends to begin with.

Seonghyun and Nambong are chatting when they notice a fight breaking out. Seonghyun explains to Nambong that a fight is unlikely between the two, since they are only yelling and not actually preparing to fight. He asks Nambong to try and guess some clues about the people walking around him, and that he doesn't need to empathize with people in order to understand them. When Seonghyun returns from his class, he sees Nambong still observing the people. He asks Nambong if he would like to study people, since they are mostly the same.

In present day, Nambong notices that their game has still not ended, as he is still checking out Seonghyun's latest reads. He also kept the habit of observing strangers walking past him.
