Following "Became the Beijing Princess's Dog" Part 2, Kogo moves on to the next hotel. There, he is expected to serve as the princess's sexual toy—forced to lick her anus, perform cunnilingus, and undergo further training, deepening his role as a submissive pet. Yet Kogo still fails to perform well. When the princess's friend visits, he is made to lick dirt off the soles of her shoes, further reinforcing his degraded position. However, Kogo remains clumsy in his actions, unable to meet the princess's expectations. Nothing he does satisfies her, and he can't even bring her pleasure. Watching his ineptitude, the princess begins to wonder if she should really take him home. Japanese and English subtitles are included, allowing viewers to follow the unfolding story.
