Princess Ning'an of Prince Rui's Mansion suddenly heard that the emperor wanted to choose two royal relatives to marry far away. Only three years after his father and brother died in battle, Daqin fell into a situation where a woman was needed to marry him to maintain stability. Princess Ning'an was filled with grief and anger, knowing that there might be a shocking secret behind the marriage. The inexplicable deaths of their father and brother in battle would not be simple.
She responded calmly, comforting her mother while secretly planning, believing that she had a high probability of being selected, and guessing that the other person might be the equally lonely and helpless Princess Ningyang. Late at night, she disguised herself to visit Prince Ruian's Mansion and met relatives whom she had not seen for a long time. After some probing conversations, she discovered that Prince Ruian's Mansion seemed ordinary, but in fact, it hid mysteries. The precious flowers and plants in the courtyard and the numerous secret guards were all extraordinary. Everyone has their own guesses about the choice of their relatives. Prince Ruian mentioned Princess Ningming, but Princess Ning'an firmly believed that it was him and Ningyang.
