Twins Nueng and Song were separated after their parents divorced—Nueng was raised in a troubled home with her mother and stepfather, while Song grew up in a loving, stable environment with their aunt and uncle. Their lives shaped them into opposites: Nueng is bold, reckless, and flirty, while Song is kind, innocent, and well-mannered.

When Nueng gets into trouble with At, a sharp police officer, he begins to suspect her of more than just mischief. Things spiral when he mistakes Song—his brother’s fiancée—for Nueng. As Nueng stirs up more chaos, Song takes the fall, and At finds himself caught between suspicion, truth, and an unexpected connection.
