What does Kikuhiko mean by saying "what I did to your daughter" to Sukeroku?


I noticed that at the end of Season 1, Kikuhiko is at the grave of Sukeroku
and he says something on the lines of "are you mad because of what I did to
your daughter?"

What does he mean? What did he do to say that?

> Did he impregnate Sukeroku's daughter and is he making reference to that?
