I think Grace would be a the secret girlfriend of the three, but what about Madison? the whole sneaking around her father and brother with her mom helping would fit nice into the scene.
Even if the story isn't gonna have as many arcs as I predicted, the Secret Girlfriend one will happen. It's one that only makes sense with Logan, and that's a tip, lol. I have a few plots and ideas that I intend to split between Copper and Azure. Make it two objective, streamlined stories without dragging out either of them.
