Mariams twin (Alrawabi school for girls AU)

Just something random i thought of after reading a fanfic (no idea what it was otherwise i'd say the name) but what if mariam had a twin? and what if her twin was one of layans best friends? this is just an AU where things start out the same but eventually get fixed. Im planning on also writing one of what if they fixed things just the 6 of them without "mariams twin", but im just really excited about this. its my first time writing so im excited!!!
