In this chapter, we learn that Caio Xiao cares more about ulla than he does about her. Caio tells us that he used to love ulla because she is his sister, but now that he knows that she is Caio's, he wants to compete with Caio for her affections. He says that he has tried to confess his love to Caio in every possible way during their college days, but he never received a response. Now, he realizes that if he and Caio could be together, he would be able to express his love for her in a way that would please Caio.
