Summary
After having a bad summer, Harry goes to Gringots to get a new vault key. In doing so, he finds out family secrets that were buried with his supposed parents. He reaches out to his biological father for help, only for neither of them to know how to be a family. They struggle with manipulative people and learn how to love and trust each other. *Similar concept to other fic's, but its been in my brain for years so I figured I should get it out.
