A story book that Ren brought from Canada is one of Haru's old favorites and a story about a lone gray wolf who meets a human that he comes to recognize as his master. Already hating himself for making Ren say he'll be "just a brother," Haru is dealt the final blow by Seika's words. Meanwhile, Ren manages his high school life with the help of his classmate Juuzen and Kiri Kondo, a female student who had returned from overseas, but he collapses during PE class and is sent to the nurse's office.
