In a world where moonlight weaves through marble corridors and sunlight dances on crystal pavilions, two royal houses stand as guardians at the edge of legend: the Moon Kingdom, ruled by tradition and mystery, and the Sun Kingdom, famed for its valor and healing arts. For centuries, a shadow has hung over their realms, an ancient curse whispered in courtly tales, threatening to plunge both lands into either endless night.
The elders, long resigned to their fates, broker fragile alliances through arranged marriages, believing only unity could temper the worsening omens. Yet beneath the weight of duty, the hearts of young heirs remain untamed. Prince Kong of the Moon Kingdom, bearing a birthmark shaped like the sun-a sign both revered and feared-yearns for a life beyond palace walls. Across the realms, Prince Arthit of the Sun Kingdom, marked by the moon and gifted with quiet bravery, also chafes against the bonds of dynastic expectation.
As the royal summit approaches-the convergence of rulers and delegates beneath enchanted domes-destiny stirs. At the summit, amidst a kaleidoscope of cultures and secret negotiations, Kong and Arthit's paths cross. Their meeting is electric-a collision of light and shadow, marked by the same mysterious birthmarks that pulse in sync, hinting at a connection deeper than politics or prophecy.
Drawn together by an inexplicable spark, the two princes discover that the ancient curse targets not just their kingdoms, but the very bloodlines they carry. Forbidden union, once viewed as blasphemy, may now hold the key to salvation. As rumors swirl and dangers mount, Kong and Arthit find themselves not only falling in love but also thrust into the heart of a struggle that demands courage, trust, and the defiance of fate.
