At the end of the lecture, the students are asked to leave the lecture hall. The professor tells the students to look at their confidence. The students become pale, and the professor tells them not to waste time arguing with each other. He also tells them to whisper to each other that they are probably arguing about something small, and that they shouldn't waste their time arguing about trivial things. He then tells them that he and his friend, Choi Namhyun, are going to be married in a week's time. Sihyun, the senior, invites everyone to the wedding and says that he'll send an invitation to the number of the bride and groom. He says that if anyone wants to come, they should feel free to do so. He adds that he doesn't know who the bride will be, but he wonders who the groom will be. He wonders if the bride is someone that Sihyun Senior is dating, and he wonders if she's a good match for Sihyun. He's worried that the rumor that his brother's second son will be sacrificed in order to save the company is true, and worries that the family will know about it. He decides to confess to his brother when the wedding is over.
