In the Buddhist year (), social rank and tradition bars the love between two princesses. Her Serene Highness Princess Phiangrawi and Her Serene Highness Princess Sasinapha are like sun and moon; they may never exist side by side. Nevertheless, their unfulfilled love and heart's wishes weave them a path back to each other. By the Buddhist year (), a new era has dawned when they fall back into one another's orbits. Katsakorn and Athitthan happen to meet and love blossoms in their hearts once more. The path to love, however, is never easy. The two must join hands to fight for it. Even without the veil of tradition barring them, the treacherous tale from the past still has a hold on their present.
