The story is very good. You just need slightly better displays of amazement and reflection. Sometimes it gets very confusing or you clearly put them at inopportune moments that give the moment a certain strangeness. Like when Tsunade shows Hiruzen Senjutsu, you could have surprised him with her feat and put your thoughts into mentioning that Tsunade overtook Hashihama after she broke the barrier. There are also inadequate explanations, you have to know when to explain an event to the audience, so as not to make the characters confess in a timely manner what you want them to say. But the fic is very good. I am very curious about the history of the Hyuuga case and also if the protagonist is going to break up with Tsunade, I think he is a good couple. If it is because of his age, he is almost her age mentally.
