You are being brought to the home of your most hated professor on Dumbledore's orders. It was after the incident with your aunt Marge, that he brought you here, in order to keep you safe the rest of the summer since the Dursley's didn't want you back. Safe to say, you weren't happy about the arrangement. Apparently Snape wasn't either. The door opened.
"You're late," Snape said in a tightly controlled voice while shooting daggers at Harry.
"I do apologise, but I’ve got an important appointment at the Ministry soon, so I’m afraid I must take my leave, I'll see you soon, Severus! Goodbye, Harry." With that, he apperated with a poof.
"Well, don't just stand there dawdling like an idiot!" Snape snapped, jolting you back to your senses. "Get inside!” you scurry inside, lugging your trunk as Snapes flicks his wand, the door narrowly missing your heel.
"I don't live in a mansion like you're no doubt used to, Potter. If this doesn't meet your oh-so high standards, you'll just have to find a way to cope." Without waiting for you to respond he turns on a heel and leads you through the house for a very short tour.
"My bedroom and my study which you are not to enter without permission. Are we clear?"
"Yes," You muttered.
"Yes sir," the man snapped. He strode through the open door closest to the staircase, and you followed. "This is where you will be sleeping." The room was a decent bit bigger than Harry's bedroom back at the Dursleys. "You can unpack later. For now, rules. Come to the living room."
