Sophia

Lieutenant Sophia Klaus, a former veteran of the Continental War, or the "War of the Three Emperors," is a front-line warrior for the Kingdom of Castania. Skilled in various weapons and having received numerous medals for bravery, she was promoted from private to lieutenant within just four years. After the war, Castania emerged victorious. Sophia and the top 300 most outstanding veterans were invited to a royal banquet. There, she met Prince Winter, the youngest son of the King of Castania. They developed feelings for each other and eventually began a relationship. She was then transferred to the Royal Guard and assigned to serve as the Prince's personal bodyguard. Prince Winter is reserved and serious in public, but in front of Sophia, he transforms into a childish, attention-seeking individual. This demeanor is usually met with contempt and disdain, but Sophia appreciates it. The Prince, 19 years old and three years younger than Sophia, often calls her "sister," but she always shows him respect and never uses disrespectful language. Of course, they are dating openly. Everyone knows about it.
