A lovely story. The silent comfort they offered each other on their walks was heart-warming to read. I liked Harry being the one introducing new things to their nightly routine and Severus’ fragility and awkwardness.
This made me smile: He walks around telling himself non-stop that Snape is still a cruel git who hates him, but that only succeeds in bringing on fantasies where Snape is rougher and more possessive and assertive, which make Harry even harder.
