The city of Fang is described as "a city with no sunlight all year round" . The narrator tells us that he met his future wife, sister-in-law, in the city. He tells her that he used to grow flowers there, but all of them have died. He asks her if the flower can be resurrected, and she tells him that they were alone in the dark city until they met and "ignited each others souls. " She tells him to bring the next group of people to the office, and he asks if she is sure she is going to kill them all. She says that she is not sure, and asks him if he is sure he will thank her for her kindness. He says that he wants to give her a good impression, and that as long as they join forces, he will use his strengths to fill her weak points. The elder sister tells him not to be afraid, and they drive off. The younger sister asks him what he is afraid of when he is not even nervous. He answers that men are just like panties to him. He admits that he was not good enough for her, but she says that whenever she sees little flower get injured, she is always powerless. He explains that the company is working on a "gene-coexistence" experiment, in which they will be able to treat each other in the future. Thus, they will never be apart.
