“Well, Alexander, I think this just might be the year that things turn around for you,” he said, his voice gentle. Alec raised an eyebrow, turning and following Magnus’ line of sight to see the clock.

It was 12:00 am. Christmas Day.

A rush of joy that could only be attributed to the man sitting across from him shot through Alec’s body, and he offered Magnus a smile as he turned back around.

“I really hope you’re right.”

Summary:


He had been in love with Magnus for a long time, but lately it was as though the tension between them had been rising, just waiting to snap, and there was something so indescribably terrifying about jumping into that unknown that it had consumed his thoughts. Before, any relationship with Magnus other than friendship had always been seen through a lens of impossibility, but all of the idle touches and long gazes that had been occurring in recent months had Alec on edge constantly, waiting for something, anything, to happen.

Summary:


Izzy poked him in the rib. “C’mon, show us some tricks.”

“Ha-ha,” said Alec, pushing backwards on his skates. “Do you want to see the one where I fall on my ass, or the one where I crash into the side of the rink?”

“Hmm,” hummed Izzy, easily gliding along with him. Max stomped awkwardly on the ice next to her, his hand tightly clasped around her wrist for support. “How about the one where a dashing young man sweeps you off your feet?”

Alec frowned. “What–”

“Look out!”

Alec felt a body collide with his own for the second time of the evening, nearly knocking him off his feet. He staggered under the weight of a full grown man, hands instantly reaching to his assailant’s waist to steady the both of them. When neither of them went toppling down he let out a relieved sigh, breath white in the frigid air. He looked up to meet an inquisitive pair of brown eyes set into one of the most attractive faces Alec had ever seen. He nearly dropped the man.
