Tragedy

Meeting each other with similar tragic backstories... Training with each other too, becoming closer by the second. Meeting new people. Y/N and Tonjiro fight together trying to help his younger sister, and trying to avenge both their loved ones, as well as thousand of others loved ones. Going through difficult times, Fighting to the death. Are they friends by fate? Or maybe its something more than that.....
(Id also like to clarify that I'm not a professional when it comes to writing, so it would be wonderful if you guys could give me tips, point out what I'm doing wrong in my writing, ect. I really hope you all enjoy!!<3)
