Fang was initially annoyed about Noie's goal of being reborn as an insect for the sake of freedom, but eventually gets used to hearing his rambling.
If Noie's ending is viewed after his event was first selected near the end of the game, he will meet up with Fang in his room, questioning Fang about the meaning of freedom. While Fang thought that Noie wanted to be free in his next life, Noie revealed that he eventually was not convinced that there even is a next life. He asked Fang about the secret to freedom, but Fang does not even know. When Fang was about to leave to pick up Eryn, he told Noie that he can accompany him whenever he wants. Noie then concluded that making one's own decision is the true meaning freedom.
