Love in the Moonlight

After 50 years of foreign rule, Chansaeng is set to return to Nanta in six months. But General Kalong seizes power, abolishes the monarchy, and persecutes royals, leaving Chansaeng's royal family in fear. To protect their lineage and wealth, Prince Saenkaew is arranged to marry Thai Princess Pinanong and relocates to Bangkok. There, he meets Pinanong and her cousin Sasin, unaware that duty and love will intertwine, pulling the three into an inescapable web of fate.

At a Bangkok palace, a grand welcome banquet is arranged to announce Prince Saenkaew and Princess Pinanong's engagement. The marriage is not only a union of families but also a means to secure Chansaeng's assets in Thailand. However, General Kalong's spies have already uncovered the plan and threaten to interfere. Meanwhile, Saenkaew resists the arranged marriage, determined to find another way to protect his family. At the same time, Sasin begins to suspect that Saenkaew's feelings for Pinanong may not be love at all.

At the welcome banquet, Saenkaew's uncle unexpectedly appears, exposing the political nature of the arranged marriage. Meanwhile, tensions rise between Sasin and Saenkaew after a misunderstanding leads to the destruction of a precious keepsake. Feeling guilty, Sasin apologizes and tends to Saenkaew when he falls ill. A new facet of Saenkaew's past is revealed.

Amid family strife, Saenkaew grows increasingly anxious while Sasin promises to be his confidant. Back at the palace, his father's aide Kamsu arrives in Thailand, closely monitoring Saenkaew and stirring painful memories. Overhearing their quarrel, Pinanong's parents suspect Saenkaew is hiding a dark secret. Determined to expose it, they scheme to seize his family's fortune.

Saenkaew and Sasin's constant quarrels leave them both unsettled, yet every meeting ends in another fight. Pinanong tries to mediate by arranging time alone for them, but it only sparks more conflict, with Sasin pushed into the water. Pretending to drown, Sasin forces Saenkaew to jump in and save him, easing their misunderstanding. Saenkaew then reveals the truth about his political marriage and gains Sasin's understanding. But as Inthorn and General Kalong's schemes come to light, Saenkaew finds himself driven to the edge.

At the Field Marshal's residence, Saenkaew unexpectedly encounters his father, who reveals he has invited the Marshal to preside over the wedding and shatters Saenkaew's plan. Still, Saenkaew bravely confesses that he refuses to use Pinanong and the marriage to serve his family's interests, yet he is forced to follow his father's harsh orders. When his father learns Saenkaew once spent the night with Sasin, his fury ignites, leaving him to suspect the true nature of their relationship.

After the storm, Saenkaew and Sasin wake in a hut on the island, their bond charged with unspoken tension. They discuss the possibility of a fake marriage to escape Saenkaew's political engagement, but soon the rescue team sent by his father finds them. Furious at seeing them together, his father slaps Saenkaew and denounces him as disgraceful. Witnessing everything, Pinanong begins to doubt that Saenkaew and Sasin's relationship is strictly platonic.

Sasin is shot, and to save his life, Saenkaew tearfully agrees to his father's demand to go through with the wedding. But his uncle sets a cruel trap, lying that Sasin's condition has worsened, driving Saenkaew to flee the palace for a chance to see the man he loves. Just as their secret romance is about to be exposed, Pinanong appears; will she protect them from disaster, or take revenge for their betrayal?

Saenkaew's father eagerly prepares for the wedding, planning for him and Pinanong to move to Chiang Mai after marriage. However, Saenkaew's secret relationship with Sasin gradually comes to light, as rumors about the two begin to spread. Meanwhile, his uncle secretly plots to expose their affair, pushing Pinanong to heartbreak.

On the eve of the wedding, Pinanong witnesses the intimate moment between her fiancé and cousin, realizing that the two people she loves most have both betrayed her. Consumed by pain and anger, she falls deeper into despair. Meanwhile, her uncle's scheme unfolds as he prepares to expose incriminating photos during the ceremony. At the same time, Sasin plans a daring rescue, arranging for Saenkaew to use the wedding as a cover to escape, though tragedy lurks just around the corner.

As the uncle's scheme throws the wedding into chaos, Saenkaew's father accuses him of bringing shame to the family and threatens Sasin's life, forcing Saenkaew to officially marry Pinanong and move to Chiang Mai. But losing Sasin leaves Saenkaew deeply scarred — the love and happiness once shared among the three has now been shattered beyond repair.

After the marriage, Pinanong suffers from her husband's coldness and lack of love. Her father then shows her photos of Saenkaew and Sasin kissing, ordering her to go through divorce and seize the family fortune. Realizing that Saenkaew and Sasin's love is sincere, Pinanong decides to upend her father's scheme.
