She wouldn't be allowed to keep running it.

''Your bread stall? Hm... Well... You would have to live in the castle and take care of my needs, so running a stall is out of the question... Your bread was delicious though, better than anything I have had in the castle so perhaps... I could convince my father, the king, to have the head butler serve your bread frequently at the castle. Would that be enough?''

Grace gulps, ''M-maybe...'' She whispers.

You smile, ''Good! Then it's settled! You are coming with me to the castle!'' You announce.

Grace gulps, ''W-wait... What if you tire of me?''

You shake your head, ''This again? I won't get tired, trust me. Besides, working as a maid for even a single year in the castle will likely bring you more benefits than ten years of selling bread.''

Grace bites her lip nervously, ''I-I d-don't know...''

You smile at her, ''Then you should think about it carefully, because I'm going to take you to the castle whether you like it or not.'' You reach across the table and hold her chin. ''You see, I'm a selfish prince... I think I might just found something I like, Grace. You.''

She blushes and looks away from you, unable to meet your gaze.

''Look at me, Grace.'' You speak to her softly. ''You'll be living in the castle. You will eat wonderful food, wear pretty dresses, and every night you will go to bed knowing there's food on the table.'' You smirk at her. ''You'll be serving a prince, and not just any prince either... Our servants tend to have good working conditions but I... Well, let's say that I have a closer relationship with my servants. You won't regret it, I promise.''

Grace blushes, ''U-um... Yes, sir...''

You kiss her on the forehead. ''Perfect, good girl! I'll order us something to drink. I need some wine to wash down that chicken.''
