Generally when I get a new idea for a project, I run it into the ground until I get bored of it (which happens quite quickly), and then I leave it on hiatus indefinitely. Until I suddenly get another burst of inspiration, and then start up all my old projects again.
Anyway. Previously on Nursery Rhyme, Shizuma got conned into a date with Yukina, or at least what amounts to a date. This doesn't actually have much to do with the plot, since it's not like the player can choose to get out of it.
