Falling for the protector part 1

I do not own this picture. it was created by someone else. I hope you like the first part of this story ^^ there will be more.
As a side note if someone can tell me why it's named falling for the protector I will give one free full body, full color commission!!
(only applies to the first person to get it right sorry )
as another side note, the (------) is to represent when the main character switches.
