@dartis I disagree, i feel that chapter 1 was essential to the ongoing story. The personality of each character is established, we see how they interact with each other, their motivations, how exactly F and D went from not having seen each other for 10 years to kissing, fondling and masturbating each other.
Would you really be satisfied if at the start of chapter 2 there was just a blurb saying "you are <name> your relationship with your wife ended badly and she left the country, taking your daughter with her. After no contact for 10 years your daughter showed up at your door. Over the course of 2 weeks you went from being her father to being her lover. Now your ex has taken her away again, how will you get her back?"
Simply reading a background isn't the same as experiencing it. We've now seen HOW the relationship developed, we're invested in the characters.
