To answer why he didn't marry her after his brothers death; it was illegal to marry a deceased brothers widow in the 1800’s. And strictly prohibited by the church. Bastard children or children born from adultery rarely inherited titles or wealth. Also titles belonged to the king so if they created a large enough scandal, they could have lost their ancestoral land along with their titles so a lot of reasons to keep all that secret.

I really liked this one. I've read so many shorts that pack too much in and then make the pace too fast to enjoy it. The pacing in this feels just right; I got a whole damn story with plot and smut and then bonus sides. On top of all that the writing, art and translation were perfect. You don't come across gems like this all the time.

I’ll definitely reread this one; it has a real plot and doesn’t have to rely on smut. Not that I mind some good smut. Sometimes, I read for the smutty stuff, but this story made it feel like a bonus on top of the good storyline. I did notice the art change, and I’m okay with it. It often bothers me, especially if it goes bad; I love it when you see a progression in skill and the art improves. This one almost felt like two different artists, but both art styles were lovely, so I was happy with it. I think this one is worth a second or third read.
