Boy and girl grew up together as best friends in a small town. Boy claimed love for girl but she turned him down and his parents moved away shortly after. She ended up staying & becoming the town vet(?). Now he's back in town for their ten year reunion, along with the rest of her class.
After that it could go in any direction. Solid romance where they rekindle their love, mystery where someone at the reunion gets murdered, supernatural where there's a witch who is trying to get revenge.... the world is yours!
