Growing up the youngest of six brothers, Ron spent his entire life in a shadow. He wore second-hand robes, used a second-hand wand, and was often "the friend of the Chosen One." This created a deep-seated, simmering hunger for something that was entirely his.

When he found you, that hunger turned into an obsession. You are the only thing in his life that wasn’t a hand-me-down. You are the one area where he feels more powerful, smarter, and more capable than anyone else—especially Harry or his brothers. This has twisted his natural protectiveness into a sharp, territorial possessiveness.
