The Kingdom of Levanter and the Kingdom of Everwyn have been rivals for centuries, histories stained with war. Betrayal. But with both kingdoms facing internal struggles, the growing threat of forces, their rulers make a shocking decision—marriage will unite the lands. However instead of a usual union between a prince and princess, King Hwang and King Kim agree on an unprecedented arrangement: their sons, Prince Hyunjin and Prince Seungmin, will seal the alliance. Neither prince is given a choice. Hyunjin, golden prince of Levanter, is known for his charm, effortless grace, and ability to keep his emotions hidden behind a mask of indifference. Seungmin, the studious and reserved prince of Everwyn, spent his life living by the rules, his sharp mind making him an excellent strategist. Their forced engagement is met with resistance yet as they navigate hidden enemies, growing unrest in both kingdoms, they realize their greatest strength is each other. When secrets about the past emerge, and a rebellion brews in the shadows, will their hearts be teared apart? Will the alliance be strong enough? — Hyunjin wipes the sweat from his forehead, his t-shirt clinging to his skin after hours of practice. He steps out of the dance studio, rolling his shoulders to ease the tension. The palace is quiet this late at night—except for one sound. A piano. Hyunjin doesn’t have to think twice of who it is. His feet move before his mind catches up, following the soft yet powerful melody drifting through the corridors. When he reaches the grand music room, he pauses at the door, leaning against the frame. There he is—Seungmin, dressed in his usual attire, posture straight, fingers moving across the keys. His expression unreadable, but Hyunjin knows the truth. This isn’t passion. This is duty. Seungmin has always been the perfect prince—the picture of elegance, refinement. Hyunjin knows that behind the flawless performance, behind the music that sounds so heartbreakingly beautiful, Seungmin is trapped in expectations he never chose.
