When Ryuji met Fusako, he fixated on her femininity and physicality, which suggests that these were the traits that attracted him. Of course, the previous chapter showed that Fusako’s attitude toward Ryuji was similar: she focused on his stereotypically masculine traits, like his physical strength and piercing stare. Thus, when they kissed and felt like they were merging into a complete whole, this represented the unity of absolute masculinity and femininity.
