Snape X Reader (I'm With You)

"Well, if it isn't Snivellus! Fancy meeting you here!" Potter snickered as he walked up to the shore of the lake, where Snape had been studying his Ancient Runes. 
"What do you want,Potter?" Snape asked as he raised his wand,prepared if his enemy was going to attack him.
"Oh, I want absolutely nothing! It' just that someone else has a "Bone" of sorts to pick with you."
After he said that Severus found himself being attacked from behind. His wand fell from his hands as a pair of muscled arms clutched around his neck in a choke-hold. 
"Hello Snivellus."
"B........Black! What do you want?" Severus stuttered as Blacks arms became ever tighter.
"Why would I need a reason to visit my favorite punching bag?" Black smugly said as he raised his wand to the smaller boys neck.

"POTTER! BLACK! KNOCK IT OFF RIGHT NOW! IF I EVER CATCH YOU AROUND SEVERUS AGAIN, THEN I'LL TELL THE HEADMASTER! NOW BACK AWAY BEFORE I HEX YOU!" you shouted as you ran to help your friend,your wand raised. Potter and Black knew very well that you would be true to your word, and reluctantly threw Severus to the ground before running up the hill to the castle. Severus fell to the ground in a heap as you rushed to his side. His face was bloody and there was a large bruise on his forehead where he had hit the ground. You quickly said a healing spell , then watched as the blood and bruises receded and he slipped back into consciousness.

"______." he stammered, "W..Why do they keep doing this to me? What did I ever do to them?"

"They're just evil. Don't listen to them, Sev."

"But you'll never leave me, r.......right _______?" he asked as he was helped up by you.

"Never. You're my best friend." you said as you enveloped him in a hug. He hugged back as a small tear cascaded down his face.
