Yeah, but then she would be related to Ml and I'm not sure if I like that, and I think it would be refreshing for her to be a nobody and not some secret princess.
The original princess was actually related to him though, they're cousins but I get what you mean
she's not just a servant. given her similar features to the emperor, she could be a half sister of the princess - or her parents were related to royalty somehow - and do have a claim over the throne to become empress. This is how stories like this usually go.
