I chained an all-powerful dragon king from an enemy country to myself. I just messed up a summoning ritual by accident—because I wanted to avoid marrying some old geezer. Now the dragon is furious, because the bond interferes with his plans to marry. I have to find a way to break the spell that binds us—because this dragon is monstrously dangerous! And, on top of that, he’s so beautiful and irresistible that I’m haunted by another fear… What if I fall in love with him? After all, a human and a dragon marriage is impossible.*A one-hundred-percent happy ending.)
