Checked the comments and didn't see anything so some feedback.
Pg. 13
"Should I put an end to it?"
This doesn't make sense in the context of the conversation, "Should I put and end to them?" would fit better as he's talking about the fiancé's families who didn't show for the funeral and felt relieved about his brother's deaths.
"Oh that's unacceptable young master. You're thinking of killing it off aren't you?" again, doesn't make sense in the context off the conversation, "You're thinking of killing them off, aren't you?" fits better.
I'll post more if I see anything, thanks for translating.
