Notes: After the war, Snape's put under a very particular spell to ensure his safety. When Harry comes back from his self-imposed exile he finds the man under it and soon, the spell becomes as unbearable for him as the man once was. I quite liked the desperation a spell that does not just only impede your use of magic but also touch of any kind, isolating the person under it terryfingly. I liked how it worked here and god, I loved Luna.
