Kou had a nightmare before, when she was little. Her nightmare was a nightmare version of her own Mother, she had been having these nightmares until she eventually faced them, but her nightmare lurks deep in her thoughts always there…While Kou was living a happy life her nightmare decided to form her own reality, a reality where it was wicked, an reality where she can bend it herself and to escape and go into reality. This time she wasn’t just an hallucination, she was real…Her reality was about Kou’s trauma and her nightmare made Kou’s trauma into something more terrifying than the trauma itself, she would make a plan to make them go into reality. It has failed but, because they weren’t that capable to be able to go into reality, but Kou’s nightmare was her nightmare was capable enough to go into reality. And the nightmare was able to transform herself to look like Kou, a doppelgänger of Kou.
(I make Kou suffer a lot in my AU😭)
