A ninja must see underneath the underneath

The story starts right after the battle at The Valley of The End where Naruto battled Sasuke right before he joined Orochimaru in order to gain more power. Sasuke pierced Naruto's right shoulder with his Chidori technique. My story deviates from the canon series because Naruto's wound was not immediately healed by the Nine-Tails. Also, Naruto didn't go into his initial junchūriki form, as he refused to use the Nine-Tails chakra. The story starts with Naruto recovering from that fight in the hospital. Afterward, he is sent on a 2-year mission with his sensei Kakashi Hatake. As they travel together, their bonds grow stronger until they eventually learn about each other's true feelings. (Yaoi and violence!)

! - I do not recommend reading this story if you are not familiar with the series.
! - In this story, Naruto starts off as a 17-year-old, not 14 as in the series.
!- The story continues until the canon's Pain episodes, so if you haven't seen that yet, there will be spoilers here.
!- Yaoi lemon in later chapters. The KakaNaru relationship evolves from teacher/student to friends (bromance) to lovers while they travel together.

I started writing this story because I'm a big fan of the Naruto series. However, there have always been two things bothering me. For one, the filler episodes and constant flashbacks of course, and secondly, the lack of relations. For example, Kakashi not caring all too much about Naruto's upbringing even though he is Minato's son. Or the fact that nobody (not even his godfather Jiraiya) adopted Naruto. And don't even get me started on the fact that nobody ever told Naruto anything about his parents, nor did he ever ask... Anyway, the list is long.

It's my first time writing fanfiction. Obviously, I do not own Naruto or any other characters from the series/manga. My native language is Dutch, not English, so please try and forgive any spelling mistakes you might find. Feel free to inform me on them if you'd wish to do so.
