Original Description:
 
as long as i exist ill never going to draw these two loving eachother  
I love so much the rivarly they have its so lovely idk how to explain it, I adore them better being against eachother than being the perfect sister couple they are.  
No one never forgets their past and luna never will forget nor forgive
 
What I was visioning is that nightmare realizes that no matter how much time and time again celestias promised her she will have equally everthing as her and become a team they always praised her sister more. thus her turning back into nightmare moon and confronting her yelling at her LIAR over and over again. Celestia isnt realizing what went wrong and screams and cries in frustration apologizing, not knowing exactly what upsets her sister, in the end that made nightmare more upset since celestias doesnt know why is she apologizing.
