   Summary

   In which Nightmare's gang and the Stars each fall in different ways.

   Nightmare (and all their lovers) can't help but fall for Error, their current guest and target for love and support.

   And the Stars? Well, the right thread's been pulled, and they're falling apart.

   This will be written in a series of one-shots that are not chronological, with the first couple originating from Lover's Stories. You can find the timeline here. Chapters with triggering content will be marked with a *. I'm working on adding summaries to the end of triggering chapters but be aware that I'm not the best at including all the important details or writing summaries ^^'
