It's also the week Flora's life unravelled.
For Flora, this is a chance to change her future: win back the love of her life, stay friends with her former best mate and succeed in landing her dream job. It should be easy. But her ex's best friend, Lance Devic, who she never really noticed before, keeps popping up and messing with her head. And after a while Flora begins to wonder if living in the past really will deliver her the happiness she seeks?
