I'm Falling For My Guardian, The Ghost?✔

Elizabeth is moving from Newtown to Greenside (a quiet little town in the middle of nowhere) and thinks that the move would make her life a better place. Exept for the fact that she finds out she has powers that are very rare to human beings and that she can destroy demons and evil spirits with a flick of her wrist. Elisabeth makes some friends but when she finds out that her ex, Caleb Tropez has also moved to Greenside, things are starting to get weird around the town, the teachers act differently and her friends go missing, all the answers are known by Calvin, a 18 year old ghost boy who for some reason, lives in a creepy old mansion somewhere in Greenside and wants to protect Elizabeth with his, afterlife?
