Ngao Ruk

Tatiya is one of triplets. She pretends to be her sister in order to find her sister's husband who was missing. She moves into his family's house believing that Witsanuwat, the husband's older brother, killed him for the inheritance. Meanwhile, Witsanuwat doesn't believe that Tatiya is his sister-in-law and lied to her about where his brother was. But the truth was the younger brother was crazy because he misses his wife, so Witsanuwat hid him away from society. He has a reason for not trusting Tatiya's stories, because there were many occasions that other men claimed to be her husband or that they slept with her.
