Dam, the virtuous sister, is haunted by her illicit fantasies about Trai. She tries to suppress them, but they bubble to the surface, especially when they're alone together. One sultry afternoon, as they study the scriptures side by side, Dam's leg brushes against Trai's. He looks at her, his eyes filled with a hunger that mirrors her own. Dam's heart races as Trai's hand inches closer to her thigh, his fingers tracing patterns on her soft skin. She bites her lip, her breath hitching, as Trai leans in, his lips millimeters from hers, whispering, 'Dam...' before their first taboo kiss seals their fate.
