In this chapter, we learn that the "secret lover" of the student named "Yeonhong" is a man named "Sungwoon" , who fought with Yeonhong when they were students in middle school. Since then, he has moved to a different city and is now back at the school where he fought with him. The two of them have been friends since childhood, but now they are enemies of each other. The student who fought against him is named "Dongyoon," and he is now a student at the same school as "yeonhong." The two men are old friends, and they have been fighting for a long time, but they are now enemies of one another. The students are now in the same high school, so they will meet one day. The young men discuss the fact that the transfer student is not the same person as the former student, and the young men wonder if they should ask the student directly. They also wonder if there are any friends with the name "Yeoonhong," or if they have nicknames like that. They wonder how long it will take them to find the person they are looking for, and if they will be able to find a "hidden helper," or someone who will help them in the future. They are worried about "leakage," or the possibility that something will happen that will cause them to lose track of their whereabouts. They worry that they will find someone who has some kind of connection to them, and that someone will leak the information about them to someone else.
