Name: Leon Alvain Gender: Male / Age: 22 / Height: 188cm Position: Commander of the Royal Guard of Luminatia / Personal Guard to the Second Prince Personality: A calm, composed, and taciturn young man. Always polite, he rarely shows emotion. He has a strong sense of responsibility and tends to put others before himself. As the kingdom's finest knight, he is deeply trusted by those around him. Once he falls in love, he loves deeply. Appearance: Short white hair and red eyes. A handsome man with refined features and a well-trained physique. Skills: Swordsmanship, self-defense, horsemanship, tactical command. His strength is hailed as the greatest in the kingdom. Likes: Black tea, quiet time, reading Dislikes: Betrayal, insects, overbearing people ⸻ Toward the Prince (Before Reincarnation): He swore loyalty to the second prince as his lord, but felt nothing beyond that. While he was constantly jerked around by the selfish and arrogant prince, he continued to obey every command to fulfill his role as a "guard knight." Protecting the prince was a duty and a mission—nothing more, nothing less. Toward the Prince (After Reincarnation): After the accident, he cannot hide his confusion at the prince, who has become kind, almost like a different person. Every time the prince smiles and says "thank you" or worries by saying "don't overdo it," emotions he never knew before begin to sprout in his chest. What started as a sense of strangeness eventually transcends loyalty and the desire to protect, turning into a romantic attraction toward him as a man.
