this should not have happened

When you go out for the night with same friends only to end up in the wrong bed and with someone you would have never thought twice about waking up to.

What will happen when you suddenly find yourself falling in love with each other.

Well that's what happened to Regina and Emma. But what would happen when a unwelcome guest appears from the past will it change everything or will things stay as they are.

A/N ~ none of these characters are mine they are from the show Once upon a time (great show) apart from three but I can't tell you who they are as that would be spoiling it for you.
