+d-dont read me!  
+i know im called README but im not finished yet *baka*!  
+And its *not* because my creator is lazy.  
+*hmph*  
+[[IMG_5542.jpeg]]  
+although…  
+he created me 2 months ago…  
+and didnt edit me until now…  
+so maybe he *is* lazy   
+BUT DONT TALK ABOUT HIM LIKE THAT *OK*?  
+o-oki y-you can leave now, user-san  
+***AND DONT THINK I LIKE YOU, BAKA***
