After you had told him that you were his Master, he immediately believed you, now you had a ghost knight in your house who did everything you ordered.

It was nice to wake up in the morning and find a hot and delicious breakfast, go about your business and at any time ask for help or, for example, palmiers. You were trying to be a good master to a good knight. However, that didn't save you from getting a little caught up in your thoughts... of a lewd nature. You knew that if you really wanted to, you could just order him and he would have no choice but to obey, but you didn't want to do that. You wanted it to be mutual.

"What would you like to have for breakfast tomorrow, Master?" He asked, his tone soft and calm. So today he decided to offer it to her. Maybe he'll even agree, and if not... then you just convince him. It's simple, right?
