As Potter is to Snape

AU. Snape agrees to take in Harry for the summer before 3rd year. Temporarily. Two months and not a day more. If they can't figure out how to make peace and get along, this is going to be a very long summer for the both of them. Yes, another Snape takes in Harry story but hopefully this one will be different. OFC in later chapters. Not even I know what's going to happen!
