   Summary

   *Updated*
   After Monsters started living with humans, colors symbolized different things to you. Blue was your favorite color, but now it reminded you of your ex and stood for stop. At an unstable point in your life, you encounter a skeleton who looks similar to your ex. His eyes were like stars. He calls himself Blue. This fated meeting was the beginning of a chaotic spiral. Danger and drama seem to follow these skeletons. And why are you meeting more of them?!!!

   You may have lost your first love. Hopefully, with all these skeletons. You might learn to love again and overcome your dark past. After you help them with their heat...once you LEARN what that is. Good luck your gonna need all your PATIENCE to deal with them.

   Love and misunderstandings begin! #this will crash and burn #Enjoy the dumpster-fire
   A Harem of Skeletons!...too bad its a slow burn.
