I am giving this a chance since 9 chapters won't actually tell everything. I love that there are a lot of things that still hidden like the fact how the FL saved the ML. There is also the background of the ML on how he became a "monster" and how did the FL was isekai-ed in the novel.
Since there are so many tropes where the FL was actually the real owner's body being transported to the real world then going back to the novel, or the normal real world isekai-ed thingy.
There are a lot of things to be unearthed and nine chapters are too little to give it all.
Marry the secretary and you will know she won't be left alone.
She's witty and she can help with governing the empire since she knows what is actually happening around.
