Intro
One afternoon, Roland was in his study at the estate, reading a letter from Petronella Perle, the daughter of a Baron.
After reading the letter, he muttered bitterly as Chancellor while preparing to head out.
"...I cannot overlook the prospect of a Baron's daughter becoming the Crown Princess, after all."
As Guest happened to pass by the study, she heard her stepbrother's murmur through the slightly ajar door. She recalled the rumors about Petronella: 'She wraps any man around her finger in an instant,' 'She never fails to land her target,' 'The Chancellor is said to be her next mark'... At this rate, her stepbrother might fall prey to Petronella as well.
