I don't really know much about it. Maybe it's a story full of adventure and exciting characters. It could have a unique plot that makes it stand out from other novels.
Well, in this kind of story, the man could also be a symbol. He might represent a new beginning or a connection to a different part of your family's past that you were not aware of. He could potentially bring some closure to the whole situation of your dad's passing by sharing important details or just by being there at such a crucial time.
One potential impact could be on the family's reputation. People might judge the family differently. But if he uses a pen name, it could reduce that risk.
Once, I participated in a school competition. I was so nervous. My dad noticed and he gave me a pep talk before the event. He said I was the best no matter the result. During the competition, I could see him in the audience cheering me on with the biggest smile. That really boosted my confidence and I ended up doing great.
My life story is a bit of a journey. I started with big dreams as a kid. I studied hard in school, though it wasn't always easy. I worked various jobs to support myself. One day, I saw your mother across the room at a party and that was a turning point in my life. We started a family, and I've been working hard ever since to give us all a good life.
