Dear Diary (A Reader Insert)

You find a collection of diaries in the attic of your new house that you just bought. You try to contact the former house owners, only to find that they died from a flash flood - the same one that happened to ruin your house, which caused you to buy the new one in the first place. The neighbors say that the girl who wrote in the diaries was a witch who practiced water magic. Curiosity getting the better of you, you choose to read the diaries in order to find out if the girl had something to do with the flash flood.
