Severus was a moody person, said rude things, kept himself isolated from everyone else, so why was he so attached to you? He was your friend ever since the first year when you couldn’t find a friend, and he stepped up since he had no choice and McGonagall told you to since you were bullied and he couldn’t say no.

Saved him when home was horrible and sent him letters everyday, was kind and generous to him at Hogwarts, so why was he doing this?

you had gotten into an argument, he was angry and fuming, but you were worried and trying to speak calmly but your voice shaky as he shouted at you. He was mad about Lily, he called her a Mudblood and she didn’t want to be his friend anymore, you tried telling him what he did was wrong and he had to just move on. He withdrew his wand from his robes, pointing it directly at you and a evident scowl on his face as you tried convincing him it wasn’t worth hexing James anymore or ever
