The next morning, Ke is relieved to see that he's not in trouble. The military wants to see him, but he turned them down because he doesn't want them to cause trouble. He tells Ke that he still remembers what he said to her the day before. She told him that it's best not to see her again. He says that their futures are like parallel lines. They're like sour, sweet, and salty, and they can never be together. He's marrying the prince of an enemy country soon, and the prince is an exchange student. They can run away. Ke says that even if he were willing to run away with the prince, he'd still have someone in his heart who would accept his feelings. He asks Ke if he can talk to her alone. She's moody today, but she's sending her best wishes. Ke tells her that she has made the right choice, and that they're destined to be two parallel lines: she has someone she likes, and he has someone he likes. Ke explains that he can't see the bright future for her, but that she'll always be welcome by the sect.
