When Sonic was young, her friend gave her a necklace. When she gets older she doesn't remember who gave it to her or who had the other half of it, but in turns out to be a big mystery. (There might be a second part too)
Sonic finds a weird red ring that causes him to act strange. And the more he sees Amy the crazier/obsessed he gets. Will Sonic do something to Amy? What will happen ?
