※This article contains spoilers. tvNTV Series "Graduation" EP4 (viewer rating 4.8%) features only one student, Hye-jin (Jung Ryeo Won), who visits the school.
The lecture of Junho (Wi HaJun) was described. Finally, the day of Junho's free lecture event has arrived. "There are times when you suddenly get flustered and can't speak well.
"Look. I'll feel a little better when I see the faces of people I know," JUNHO replied, "Apart from being a little excited, I'm fine. It seems like the teacher is more nervous than me..." and showed his composure. "Yeah, I guess so," he said with a laugh.
Hyejin admitted that it was an unforgettable memory of victory and took Junho's offered hand, saying, "Let's try making it."
However, not a single student showed up for the lecture.
"The attendance rate is 99%. Seo Hye-jin's lecture will end in failure," said Ki-seong (Lee Gyu-seong), who is a member of the 1st generation of the 1st generation of the 1st generation. Hyun-seong (Seo Jeongyeon) replied, "That's tough. I worked hard to prepare."
He smiled with satisfaction. He had prepared a special lecture to coincide with Hyejin's free lecture. Hyeon-tak (Kim Jung Tae) said, "What do you mean? There are so many applicants that we have to admit them on a first-come, first-served basis.
"Didn't he say that?" the assistants were surprised and whispered, "It seems that the 'master and disciple's attack' didn't work out."
When Si Woo (Cha Kang Yoon), who came to scout the place, said, "I heard there was a free lecture here, so I came here," Hye Jin turned pale and said, "I'm sorry. I'll just go and talk to that student.
He said, "You can take the materials with you," but JUNHO firmly stated, "I'm going to teach the class. You came here to take our class, right? I have to."
