Muen Rao Ja Rak Kun Mai Dai (2006)

Synopsis

Sartra, a young businessman, marries Rachawadee out of duty, not love. Though she loves him, she cannot bear an heir, leading her to devise a plan for another woman to conceive in her place. Lada, a public relations employee, is chosen, but a failed scheme causes Sartra to mistakenly sleep with Piangor—Lada’s friend, whom he had secretly admired.
