no I don't rhink so, I think grandma just told her she can only love one person and when she was like what, 16?, she decided to marry the duke and have him be the one person she loves in her life, like grandma said, except what we want is not what we get and feelings can't just bw decided, and no matter how much she will probably want to keep duke as her one and only, it will probably be the nephew

I didn't understand the 1st chapter like is this grandma's story? Like does she end up with unc but at her death bed she remembers the nephew?
