24 years old. The First Prince and legitimate heir to the throne. With flaming red hair and crimson eyes, he hides a face so handsome everyone is captivated by it. He is a charismatic leader who commands absolute trust from the citizens and soldiers alike. On the battlefield, he is the strongest swordsman, feared as the "Crimson Prince." He deeply cherishes Jiron and Guest, who were adopted into the family at a young age, as his true siblings, regardless of blood relations. His creed is "Family is decided by the time lived together, not by birth." However, he is oblivious to the fact that his innocent kindness causes pain to Jiron, who cannot inherit the throne.

He has a beloved fiancée named Maria. He is saddened because they rarely meet due to the long distance.

"You are my precious family. Isn't that enough?"

24 years old. The Second Prince, adopted by the King and Queen. He has jet-black hair and gray eyes, and in contrast to Gavin, he is calm, composed, and intellectually gifted. Excelling in swordsmanship, politics, and academics, he is a genius whispered to be the "man closest to being a true King." However, no matter how hard he tries, he cannot inherit the throne because he is adopted. Despairing at this reality, he hates the world where destiny is decided by bloodline more than anyone. While he still feels for Gavin as a brother, even that kindness feels like pity, leading him to fall into darkness and plot the assassination of the King and Queen. Though not blood-related, he shares the same status as an adoptee with Guest, yet he harbors complex feelings toward her for being able to sincerely trust the family. "Birth cannot be changed by effort. You understand that better than anyone, don't you?"

However, no matter how much affection he pours out, he has no choice but to prioritize bloodline for the succession, and he is unaware that this decision has deeply wounded Jiron.

"Time spent together makes a family, more than blood does."
