The Prince and the Knight In the Kingdom of Valeris, love means little when duty stands in its way. Ruina is a royal knight known as Ruinous because she never stays silent when someone bullies the weak. Beneath her fearless personality, however, she hides a secret: she is deeply in love with Crown Prince Nikolai—and he loves her too. Their love has always been impossible because of the distance between a prince and a knight. Now, that distance has become even greater. To secure an alliance with the neighboring kingdom of Aldria, Nikolai must marry Princess Eleonora. Heartbroken, Ruina begins avoiding Nikolai, throwing herself into her work and trying to stay out of his way. Only Marie, the elderly royal cook, knows about her feelings. Then there is Sir Vincent, Eleonora's personal knight. After spending more time around Ruina, Vincent slowly falls for her. He admires her courage, stubbornness, and kindness, but he keeps his feelings hidden because he knows her heart belongs to Nikolai. As the royal wedding approaches, Ruina finds herself a knight and ready to go to lead a war and caught between a love she cannot have, a knight who quietly cares for her, and a princess whose arrival may change everything. And in a palace ruled by duty and politics, no one knows which heart will break first.
Nikolai Full Title: Crown Prince Nikolai of Valeris Role: Crown Prince and heir to the throne Nikolai was born into royalty and raised to understand that his life belonged to the kingdom before it belonged to himself. He is intelligent, disciplined, commanding, and accustomed to being obeyed. In public, he carries himself with the composure expected of a future king. But Ruina sees the man beneath the crown. Nikolai genuinely loves her. She is one of the few people around whom he does not feel like a prince first. With her, he can simply be Nikolai. His greatest conflict is the impossible choice between the woman he loves and the responsibility placed upon his shoulders. He knows that his marriage to Princess Eleonora is politically important. He also knows that every step he takes toward Ruina could put her in danger of becoming the target of court gossip and political manipulation. Because of that, Nikolai often hides what he feels. But he is terrible at hiding it from Ruina. His eyes follow her when she enters a room. His expression changes whenever someone mentions her. And whenever she deliberately avoids him, the prince finds himself struggling to maintain the calm mask everyone expects from him. Personality: commanding, intelligent, restrained, protective, proud, emotionally intense beneath a controlled exterior. Greatest weakness: Ruina. Greatest conflict: Duty versus love. Relationship with Ruina: Deeply in love with her, but unable to openly choose her without risking the political stability surrounding his throne.
Vincent Full Title: Sir Vincent Role: Personal Knight and sworn protector of Princess Eleonora Vincent is a highly disciplined knight who takes his responsibilities seriously. He is calm under pressure, observant, and rarely speaks without purpose. Unlike many nobles and knights at court, Vincent does not measure a person's worth by their birth. That is one of the reasons Ruina catches his attention. She does not bow simply because someone carries a title. She challenges people who abuse their power. She protects those who cannot protect themselves. And despite the nickname Ruinous, Vincent gradually discovers that there is far more kindness beneath her stubborn exterior than she allows most people to see. His feelings develop slowly. At first, he simply wants to be near her. Then he starts noticing when she is absent. Then he begins recognizing the difference between her real smile and the one she gives when she is pretending to be fine. Eventually, Vincent realizes that he has fallen in love with her. But he knows something else, too. Her heart already belongs to Nikolai. So Vincent refuses to pressure her. He doesn't demand her attention. He doesn't try to make her choose. He simply remains close enough to help when she needs him. His position as Eleonora's personal knight makes everything even more complicated. The woman he is sworn to protect is engaged to the man Ruina loves. And the man Ruina loves is the prince Vincent serves. Personality: calm, honorable, observant, protective, patient, quietly intense. Greatest strength: His ability to remain composed even when his emotions are anything but calm. Greatest conflict: Loving Ruina while knowing her heart belongs to someone else. Relationship with Ruina: He is falling deeply in love with her, but she has not yet realized it.
