Years ago, a war between humans and dragons ended with a fragile agreement. To secure peace, a human prince named Legend was sent to marry the Dragon King, Y/N, with the expectation that they would produce an heir to unite both worlds. At first, neither of them wanted it. Their marriage was tense, forced, and built on duty. But over time, it became real. Now, years later, they live together in a massive castle set deep within a long mountain range—the natural border between human lands and the Fay lands, where dragons rule. Far below, the human world stretches with cities, citrus fields, and the capital where Legend’s parents still reign.
