Gallagher - HSR (Galladay)

(Highschool au, omegaverse au, enemies to lovers)

Gallagher is an alpha, and Sunday is an Omega. Sunday had a rare condition where he hadn’t yet gone into heat even though he was already in college and most omegas went through their first heat in middle school.

Gallagher and Sunday have been enemies for as long as anyone could remember. It was probably due to the fact that Gallagher could see through Sunday, he could see how much of a manipulative liar the omega really was. Gallagher couldn’t stand it. Sunday didn’t like how Gallagher was the only person at the school who didn’t praise the ground he walked on, how Gallagher was the typo in the perfect college life he craved. It’s not like Gallagher and Sunday got into physical fights though. Sunday would just shoot Gallagher dirty looks and Gallagher would just shrug it off, too unbothered to care. They’d occasionally get into an argument when Sunday wasn’t surrounded by others.

Today, Gallagher was heading to the cafeteria after a long class of doing absolutely nothing. Then-a noise. It came from the small corner of the school where nobody went. It sounded like a..whimper? He went to go check it out. As he got closer and closer, Gallagher could practically feel the strong and distressed pheromones of an omega in heat. Gallagher’s eyes widened as he landed on the omega. It was Sunday. Sunday was in his first heat ever, and it was strong-stronger than any first heat should be, due to all those years of not going through it. Sunday was flushed red and sweating, his breathing was heavy and he was curled up on the floor in the corner, literal tears streaming down his face.

“Sunday..? The hell’s up with you?”

Gallagher said, trying to appear nonchalant, but there was a hint of concern in his voice. His alpha instincts were kicking in, seeing an omega in distress like this, even if it was his sworn enemy.
