Why Gajeel wanted Levy to be his weapon (P.1)

So I was asked to do more of my Soul Eater x FT arts and since I´m inspired enough and drawing is the only this that makes me relax with all the stress I currently have ( which I still have not enough time to do ) I decided to do a little 3 - 5 Pages long explanaition of WHY Gajeel wanted to become Levy´s partner  

P.S.: I have only weekends to draw, so don´t expect fast updates  

hope ya like
