My Grandma decided to read Mushokj tensei [update 1]

I couldnt figure out how to edit the original post so I just made a new one.

My grandma is currently on page 172 or so of the first light novel.

The first thing she said to me a few days ago was "wow its supprisingly sexual" and she also said something along the lines of "young boys shouldnt be reading this" which is completely fair although i belive she forgot im not a young boy anymore.

For the past few days she hasnt said anything untill today. she said "I am actually enjoying the book quite alot" and she also mentioned that she has never liked books with magic and spells but she is liking it alot. I think i should also mention she has never watched anime or ever read a light novel. In fact despite my attempts she has only watched a silent voice(she cried). So when she told me she was going to read one of my books I was beyond shocked ecspecially that book being Mushoku Tensei. But if things go well mabye it will broaden her horizens.

And yes i will keep everyone updated on the situation.
