Ideas for Mystrade (слэш)

This list is for everyone if you are keen to write the story base on the idea I provided here.
I am sick of finding my old notes only to find it was being deleted or lost due to this and that reason, that I have to either retype (when I still remember) or let it lost in the ocean.
So! Here we go.
Just, if you like any of it, thanks thanks! And we can either collab, or you can take it (just let me know cause I definitely want to read ‘em!)
