I feel that it's impossible to name one character I relate to, so I decided to pick several characters from Naruto. Also, I've been away for a few days so I'll be posting all my entries last minute.
I feel like I relate to Shikamaru (but then again who doesn't) I'm contantly being told that I'm smart and have lots of potential (not that I belive that...) but don't have the motivation or the drive.
On the other hand, at the same time, I feel I relate to Hinata. Trying to improve in order to be acknowledged by someone important to me (but in that respect I'm also slightly like Naruto and Lee...). I also get shy in public (which I am trying to fix) but will defend people I care about.
I also kind of relate to Sasuke when it comes to his grudges (which I am also working on).
