Shadow of the Heart(2015)

Shadow of the Heart is a Thai drama series about twins living worlds apart. Watit enjoys wealth and status in the city while Ruth works a humble life in the countryside. When Watit is attacked and left severely injured, their father devises a dangerous plan: Ruth must impersonate his brother to infiltrate his world and expose the would-be assassin. Metinee, Watit's fiancée, knows nothing of the switch. Bound by a business arrangement rather than love, she marries the impostor without suspicion. As days pass, Metinee notices subtle differences in her new husband's behaviour and character. Slowly, she begins to fall for this kinder, more genuine version of the man she thought she knew. The deception deepens as real feelings emerge, threatening to unravel the entire scheme.
