Fear
"Please don't go", Harry begged.
"I have to Harry; they are my family after all."
"Draco, it's not safe and you know it, talk to Dumbledore please. What if he knows about us?"
"I at least owe it to my mother to say goodbye", Draco's eyes were sad and fearful.
Harry pulled him closer and let his head fall onto Draco's shoulder.
"I'm scared for you", Harry whispered. "I can't lose you".
"And you will never have to", Draco said running a hand affectionately through Harry's hair.
"I love you", Harry murmured nuzzling deeper into Draco's neck.
"I love you too", Draco replied before hurrying out the door with a small smile.
Nothing could hide the fear in Draco's eyes. He was risking a lot returning to Malfoy Manor and his father's cruel control. He knew having a relationship with Harry would be risky and he was willing to face the consequences. However the fear of never seeing or holding his Harry again brought a deep horror in him that no living being should ever have to face.
