In this chapter, we learn that Cai's mind has been filled with an image of his mother for the last few days, and that this image has become his "heart's demon" . He asks his brother why it is impossible that someone would be stalking him based on his "outstanding beauty" , and his brother responds that he did not know he was "that perverted" and that he followed his mother to observe the "demon" for several days. He explains that his brother and sister-in-law have lost their mothers at an early age, and lack "motherly love" because they are too young to have a strong bond with their mothers
