When Y/N, a 23-year-old Manhattan model known as one of the most beautiful women in the world, receives an official summons from a foreign monarchy, her life takes an unexpected turn. As a child, she once held a pretend wedding with a boy she met at a park, exchanging dandelion rings before never seeing him again. Years later, she learns the ceremony was recorded under an obscure royal tradition and legally recognized. The boy she “married” is now Kim Taehyung, the 25-year-old crown prince.
