After three days, Gu has finally found his way back to the city. He's not sure how he got there, but he does know that it's because he sprained his ankle. Gu tells him that he's an ancient immortal who can protect his body from the elements, but that his body is so cold that it looks like a "cursed sigil" . Gu says that after leaving him, he started to understand why tantai and other girls were willing to follow him even if it meant their lives. Because the world is so lonely and cold, people feel creepy, Gu says. He tells Gu that the girl he loves should be like a mirror in her heart, with pure and flawless eyes and a pure heart. She's still kind and graceful, he says, even in the face of all the ugliness around her. Gu feels ashamed when he hears this, because he is not the perfect person in his heart. In the turbulent times of the world, what can he do? Not sinking into chaos, not falling into hatred, is the only thing he can do.
