I need a good story! So far, I only have a protagonist with amnesia who suddenly meets a girl that she knows but actually doesn't know since he has amnesia.

A world where magic is hidden from normal people? A world where everyone knows of magic but only some can use it? Or an ordinary world where science dominates? Or an ordinary world where science dominates but there's magic too and nobody- wait, that's been done before.
I'm open to ideas
