With a marriage proposal, the general's daughter Su Liyue was involved in the maelstrom of intrigue in the East Palace. In front of others, she is a gentle lady, with silver needles and military tactics hidden in her sleeves; while the prince hides a sharp edge in his eyes and wants to expose her "virtuous and virtuous character". In the game at the Peony Pavilion, soldiers and symbols are hidden under the chessboard; when learning the rules of the harem, she holds the princes' handles with her backhand. Do you think she is a lamb to be slaughtered? Little does he know that every step is a trap - the more he wants to control it, the more she will turn the game upside down. When the "weak woman" shows her fangs, will His Highness the Crown Prince continue to play with fire, or will he surrender without mercy?
