Change the relationships

[Diiaj]

I want to see more options for how the characters will relate to each other after they create a family. (When should I choose the status of their relationship) For example, options like sister, cousin, uncle, adopted child, mother-in-law, distant relative, and others. I also want the aunt to have the option of being the same age as the nephew (or younger), and for the brothers to be a child and an adult, for example. It should be like in real life. I hope this makes sense. I am writing through a translator.
