Well, it could be just a character moment to show the diversity of activities in the Family Guy world. Maybe she's finding an escape in the novel from the chaos around her.
It could be a form of escapism for the woman. Life in Family Guy can be quite chaotic, and a trashy novel might offer her an escape into a different, perhaps more exciting or dramatic world, even if it's not a high - brow literary piece.
Family Guy may add its own unique brand of satire. Maybe it will make fun of the typical clichés in romance novels through the woman's reactions or how she interprets the story. It could also contrast the romantic world of the novel with the often - chaotic and non - romantic world of the show's main setting.
There might not be a dedicated episode centered around Peter and a booger romance novel in 'Family Guy'. The show often throws in random and gross - out humor, but this particular combination doesn't seem to be a major recurring theme. It could potentially be a very niche or one - off joke that hasn't gained a lot of attention if it exists at all.
It can improve her emotional intelligence. As she reads about the characters' feelings and relationships, she may become more in tune with her own emotions.
I'm not sure which specific 'novel' in 'Family Guy' you're referring to. There are many storylines in the show that could involve a novel in some way. Maybe it's a novel that one of the characters is writing, like Brian. If that's the case, it could be going well or full of comical mishaps, as is typical in 'Family Guy'!
