Let's try again (sd!dream x og!nightmare x ds!dream)

Drama, angst, fluff, mention of smut ( but just later in the story ) and three multiversal leader!
A pervert birb, a grumpy chicken and goopy octopus ( + the hopeless creator with too much power, who needs a good plot for her shitty book, therefore she is going to mess up those three's lifes ).......What can possibly go wrong?

swad (sd!dream) = top
honey(ds!dream) = bottom, top
nightmare (og!nootnoot) = (mega)bottom

If because of the title you think the 3 skele were already together, but they broke up and now they want to try again then you're wrong.

English is not my first langauge, pls respect that! Noncanon things, this is my AU!!! SWEAR WARNING!!!(every character is belongs to their rightful owner)
