I'm a little disappointed with the story. What did I expect when I started reading this fanfic?
Well, I expected a greater focus on the romance between the protagonist and Tsunade, but there is almost no interaction between the two, except when the author needs the protagonist to receive a new power or ability to help with the plot. The story didn't need to be just about the romance, as that would be boring, but I expected more, not just something to be used to give the protagonist powers and abilities when convenient.
But the story isn't bad, it just wasn't what I expected to read when I saw the title.
