Your request next Carmen! I don't forget a request!

Story time! You see, there is a mirror that Lucky's friend, Gleaming Gem, owns. She keeps it in her basement, without telling a unsuspecting Lucky a special.. Quirk about the mirror. The person (or pony) who looks in the mirror will see their other half, the thing that controls the feeling you wish never existed. That, is Unlucky, which is the feelings of anger, deception, sadness, and wickedness that Lucky feels from time to time. Somehow, Unlucky was able to trick Lucky into switching bodies with her, leaving Lucky to be stuck in her world.
