Princess Jean Louise was born into an ancient French family, and her sister was sent to a convent to become a nun. The stunning Jean Louise refused to enter the convent as a nun and fell in love at first sight with Count Alexander, a courtier of the King of Sicily in Italy. The handsome couple soon entered the sacred institution of marriage. The Countess Dowager, Mother of the Count, introduced her daughter-in-law to the king at the palace, and Jean's cheerful and lively personality immediately captivated him. The king felt jealousy towards his vassal Count Alexander for having such a beautiful newlywed wife. During a fencing exercise, the arrogant king wanted the skillful Count to be his opponent. However, the Count took a two-day leave for his wife's birthday, which infuriated the king. At a masked ball in the palace, the king, disregarding his status, confessed his feelings to Princess Jean Louise. The Countess Dowager was ecstatic that her daughter-in-law had gained the king's favor, fully aware that this would bring great benefits to her family. When the Count learned that his wife was pregnant, he was overjoyed. At the same time, he noticed the king's increasingly intense attention and open pursuit of Jean. The Count felt helpless about this. One day, when the Count accompanied his wife to church, the king was watching her from the shadows with intense eyes. A nun led her to the priest, who informed Jean that the king had fallen deeply in love with her. The priest implored Jean to accept the king's love for her. Crying, Jean resented the king for involving himself with another man's wife. Soon, a son was born, and after Jean recovered, the loyal Count willingly sent his wife to the palace. Jean begged her husband not to push her into the king's arms. Torn between love and loyalty, the Count comforted his wife not to resist the king. The Count was sent by the king on a secret mission to Madrid. The queen personally visited the Countess's residence, pleading with Jean to accept the king's love for the peace of the kingdom. Meanwhile, the Countess had her grandson sent away. Jean was extremely outraged by this. The Countess coldly reminded her daughter-in-law that she belonged to the king and criticized her for her improper behavior, which had caused chaos in the court and would also bring trouble to their family. Deeply disappointed and furious, Jean hastily jumped into a carriage heading straight to the king's chambers, throwing herself into the king's embrace. The king, satisfied, allowed Jean to make all her requests, exiling the entire Count family, leaving the Count to remain in the palace to serve his own wife. Jean often took the opportunity to mock and punish her husband. Soon, at Jean's suggestion, the Kingdom of Sicily joined a military alliance against France, and the Count enlisted as a common soldier. While leading the army, the king suddenly received news that Jean had fallen ill with smallpox, which caused him to recklessly return to the palace to care for her. The prince was greatly displeased that his father was neglecting the safety of the kingdom to act as a nurse for a woman, leading to a conflict between father and son. The king, losing his sanity in indulgence, incited public anger. He fired a gun to disperse the protesting citizens. The king signed a ceasefire agreement with the French army, and Jean met her brother Charles, an officer in the French navy. Charles agreed to help his sister and her injured husband escape Italy. Nostalgic for the past, Jean begged her husband to take her and their son to France. Unfortunately, their plan was exposed, and the Count's family was captured again. To punish the Count for his betrayal, the king forced him to duel but was instead wounded in the back by the Count. The prince deposed the king and bound him to a wooden structure. At this moment, feeling hopeless over her husband's cowardice, Jean returned to the king, feeling his deep affection for her. However, the king implored her to leave Italy with their son, as he was no longer able to protect them. At the age of 23, Jean Louise returned to Paris, becoming a prominent figure in the palace and literary salons. She never remarried and passed away in 1736.
