It really depends. I need to carefully review the details of the contract first. Things like rights, obligations, and potential benefits all matter before I make a decision.
It could be that the duke had something she needed or that she was sent on a mission to interact with him. Maybe it was to uncover a secret or gain important information.
There could be multiple explanations. Maybe it's to protect someone or achieve a greater goal. Or perhaps there's a misunderstanding that's led him to act this way.
Raeliana ended up at the Duke's likely due to a combination of factors. Maybe there was a powerful force at play, or she was drawn there by a quest for something. The complex web of the story's plotlines could be the reason.
