It sounds shameless, but I got the urge to fall on her bosom as I used to do when I was a child. When I looked at the miserable figure of my father who had died by falling from a horse, I wondered why my mother and her had been attracted to such a person.

I didn’t know at that time, but he had another reason to take care of us. He didn’t have any male relatives. Therefore, he adopted me to make me an heir.
