@roxanneayy it was common for nobles to take maids as mistress or even concubines. The problem here is that Ibee was NOT acting logical.
- She made the duke search for her.
- She didn't tried to keep it secret or at least a "not so secret" so that only a close circle knew
- She flirted with other guys inside the mannor
- She never gave the duke either a yes or a no, just acted brain dead for 2 years or so
- She left the mannor without telling the duke and he thought she was in trouble so he used all his knights to search for her
The problem is that her instead of telling him "yes lets date but we must be discreet" or "I don't want to date you, please find someone else" she just pretended having brain damage and forced the duke to act more and more rash to get a simple yes/no answer.
