Yes, of course

"Yes," you answered without a moment's hesitation. "I intend to."

Your grandfather leaned back, a thoughtful expression on his face as he considered your words. He stroked his chin. "She certainly has the looks for it," the old man mused softly, nodding to himself. "The child would inherit fine traits, strength, beauty, and resilience. And she is willing."

You raised an eyebrow, tilting your head slightly. "Isn't she paid to do it? She is part of the house, after all."

"No," your grandfather replied, shaking his head. "Not the women at the establishment you visited. They are not bound or forced in that manner."

"Then...?"

"It depends entirely on her. You came to her performance. Did you think not one man in the room wanted to sleep with her? If she accepts you, it will be because she chose to, she will not because money changed hands. And from what I have gathered..." A subtle, knowing smirk touched the corner of the old man's lips. "...it seems she likes you."

He set his teacup down and rested his hands firmly on his knees.

"You and Miho don't need to marry," he declared, his voice carrying the uncompromising weight of tradition and practical legacy. "Marriage is a contract of status, but blood is a contract of nature. If this is the path you choose, then you have work to do. You will have to keep working to seed her."

He leaned forward, his expression serious.

"Do not stop until the whore carries your bastard."
