For the Young Villain’s Happy Ending

I possessed a character 14 years before the original story began. As the strongest Archmage in the Empire. [“…Protect them.”] That’s the only thing I remember. Is it a plea to protect the ending, since the novel was discontinued? It’s a romance novel. The main characters will probably have a happy ending anyway. Since there’s still time before the original story begins, I’ll just live quietly in my territory. But then I ran into him at the imperial palace. The main villain of the novel — the 4th Prince, who becomes a tyrant due to his tragic childhood. A beast-like appearance. A frail body with protruding bones. I felt bad for him, but if I change the character’s story, the future I know might change too… [“The child has never tasted warm soup.”] Feeding him… that should be fine, right? But then— “Your Highness, doesn’t it feel nice to be clean?” “……” [Abuse and neglect were a daily occurrence for the child.] That night, when I saw a servant dousing him with cold water as he trembled silently out of habit, I made up my mind. “Your Highness. Would you like to become my disciple?” I’ll make sure you have a happy ending too. “Your Highness, if you keep staring like that, you’ll get caught— by your guardian.” “That’s perfect, Marquess.” 12 years later, the now-grown 4th Prince still remained the Archmage’s disciple. “I want to get caught, you see.” Because he had realized the daring feelings he held toward his teacher.
