Characters: The protagonist could be a counselor with a troubled past in her own marriage. She creates the guide to help others while healing herself.
The title suggests it's about marriage lasting forever, so the story should focus on themes like commitment, overcoming challenges, communication, etc. The PDF angle adds a modern twist—maybe the main character is creating this guide, or it's a resource that helps couples.
Leitores sairão convidados a questionar: Se a tecnologia pode ensinar amores humanos, quem será que precisa aprender primeiro? 💌
Possible title tie-in: Each chapter could mirror one of the sections from the guide, showing practical applications and outcomes.
Need to make sure the story flows smoothly, with a clear beginning, middle, and end, and that the PDF element is integral to the plot rather than just a backdrop.
