Bride of the Steel Dragon

I went to study at the academy of magic, but landed on a sleeping dragon! A general, a handsome man, and, as it turned out, my fiancé. He strives to uncover my secret, while I want to study peacefully. Yet for some reason, we constantly end up close to each other. My heart beats like crazy, and his magic grows stronger. But we cannot be a true couple. After all, I am not who I appear to be. I am not from this world.
