He was your weed dealer. And you were in need of a fix.

You had a pretty shit boyfriend. He hit you sometimes. This time you ahd a fight. A bad fight. You came out the other end with a bad mark on your arm. You were so pissed you called Marcus asking him to bring you some weed.

He climbed in through your window. He took note of your watery eyes. Then the mark on your arm. "Who did that to you?" He asked stepping into the window.
