Alec had accepted that his mortality would always play a factor in his relationship with Magnus.

He wasn't going to live forever, and he didn't want to, but he did want to spend forever with Magnus.

He loved Magnus, there was no doubt that he did. But it always played in his mind that Magnus had had so many lovers in the past. That he only had a tiny piece of Magnus' heart.

Alec tried to voice these concerns one night, as they lay on the couch together listening to a storm outside the window.

Alec was playing with Magnus hands, only illuminated by a few candles surrounding the room.

"Where did this scar come from?" He asked, as he held Magnus' thumb in between his own fingers.

"Hmm," Magnus moved the hand forward, examining the thin white line running from the base of his thumb to the first joint.

"I think, that was from an ill-fated encounter with an ex vampire lover," He chuckled quietly to himself, as if remembering a long ago memory. He stopped when he realised Alec had fallen silent.

"Alexander darling what's wrong?" He asked, running his slender hands down the side of Alec's hips.

"Nothing, just nothing," Alec said after a pause.

"Tell me," Magnus said softly. But Alec remained silent for a while.

"Is it about the amount of people I've been intimate with?" Magnus asked quietly.

"Oh no, definitely not, I've already accepted that I've only got just a little bit of your heart," Alec said, his voice monotonous.

Before he could say anything else, Magnus whipped him over so that they were face to face. "Alexander listen to me," He said in such a quiet whisper, Alec could only just hear him. "You do not have just a little bit of my heart, you have my whole heart. I love you with my entire being and you better not forget that,"

And with that Magnus kissed the younger man softly, and the two of them fell into a isolated paradise in which only they existed and Alec knew that even for a little while, he had Magnus' entire heart.

A/N-Sorry that this isn't that well written, it's 10:49 where I am and I've just come back from a camp, so I'm exhausted. The inspiration for this story came to me while I was on camp and I wanted to write it as soon as possible. The idea for this story came from "Just a Little Bit of Your Heart," by Ariana Grande and I loved the idea behind it. So anyway hope you enjoyed and thank you for reading x
