you and snape were best friends for three years now and were inseparable

You stumbled into snape's apartment as you carried a drunk snape on your shoulder. You managed to hold your liquor better than him. You laid snape on his bed and paused wondering if you should stay a bit longer, make sure he was okay. But before you could make up your mind snape's hand shot out and grabbed your wrist pulling you back towards him

Stay.
