While insomnia is the literal condition that drives the plot, it functions as a metaphor for modern alienation. The sleepless city—illuminated by neon, drenched in rain, and populated by transient strangers—reflects a world where human connection is reduced to fleeting, transactional encounters.

The discussion of themes such as the inability to sleep in adult comics highlights the medium's versatility and depth. Adult comics are not merely entertainment; they are also vehicles for storytelling, reflection, and discussion on mature themes. They can foster empathy and understanding among readers who may find themselves or their experiences reflected in the narratives.

In conclusion, adult comics represent a vital and dynamic part of the comic book industry. They offer a platform for mature storytelling, artistic innovation, and engagement with complex themes. As the medium continues to evolve, it will be exciting to see how adult comics push boundaries and explore new territories, all while catering to the diverse interests of adult readers worldwide.
