Ryuuheika no Okisaki wa Okotowari Shitai!

However, the marriage proposal brought by her former butler—worried about her future—turned out to be for the position of the 10th consort of the King of Hybern, known as the “Dragon Emperor”! I was supposed to spend my days tending herbs in my garden and living freely with a baby dragon—there’s no way I can become a queen!!!
