Magnus watched Alec walking towards him, watched as he pulled self consciously at the cuffs of his jacket.

"I don't see why I have to wear this if we're the only ones here." Alec stopped in front of the warlock, also dressed in a suit jacket and tie.

"The atmosphere darling." Magnus leaned down and kissed Alec lightly causing him to blush slightly at his touch.

"So are you going to tell me why we're here?" Alec gestured at the room they were in. Arched ceilings curved high above them, sunlight casting colours of all sorts across the floor as it passed through the stained glass. The floor was polished wood, clicking every time the two took a step. One of Magnus' hands snaked own Alec's arm, entwining their fingers together, a smile lighting up his eyes.

"I thought I could teach you something they probably don't teach you at the Institute." He pulled the Shadowhunter towards him, feeling Alec's hand on his chest as he stabled himself. A confused look passed through Alec's blue eyes.

"Magnus I..." A kiss silenced Alec's protests.

"Alexander," He paused when Alec flinched at the use of his full name, "would I ever hurt you?"

"No, but..." Another kiss.

"Do you trust me?" Magnus spoke just loud enough for Alec to hear him. Alec looked into the eyes of the warlock, noticing the way the light reflected from them.

"Yes." That one word was all Magnus needed to hear. With a flick of his wrist music could be heard playing from somewhere behind them. Alec tried to look around Magnus to see but was stopped when a hand found the small of his back, the other clutching his hand.

"Magnus what are you...?" Magnus hushed Alec.

"Follow my lead Alec." He moved Alec's free hand to his shoulder. "Perfect." As if on cue the music took on a new path that Magnus knew how to follow. Alec felt himself being twirled around the room at the hands of the warlock. His feet moved smoothly across the floor on their own. When Magnus dipped him low he tried to squirm away so as to not hit the floor. Sensing Alec's discomfort Magnus lifted him back to his feet.

"I won't let you fall." He looked into Alec's eyes.

Colours swirled around them, darkening as the sun set. Splashes of orange and red stained the floor, lighting up the room in a display but Magnus had eyes only for Alec.

"Alexander Lightwood, you make an excellent dance partner." The two came to a slow stop in the centre of the room where they had started, the music faded until a silence filled the room in its wake. Alec's hands rested on Magnus' shoulders, he moved them to meet behind the warlock's neck.

"I love you Magnus Bane." He kissed Magnus, strong and passionate and in that moment nothing else mattered. Not the fact that the sun had set, casting long shadows across the floor. Not the fact that his family would be wondering where they were. Not even the fact that he was a Shadowhunter in love with the High Warlock of Brooklyn. All that mattered was that they were together. Magnus broke the kiss long enough to whisper in Alec's ear.

"And I love you."
