Mei//Yui

Basically, consistent dreams that is sort of like a series where the character looks and acts different in the dreams then not in the dreams, later on more lore happens but that's the base for her plot, also she has a different name in the dreams (that probably made no sense lol) btw Mei is her in her dreams while Yui is her irl. Also Yui has an older sister who I currently haven't named
