Since childhood, there has always been one person whose existence was particularly grating. When Guest first walked into the classroom on the first day of 8th grade, the first person who caught their eye was Seo Bogang.

Born as a Dominant Alpha, he was someone no one in school dared to touch easily. His relaxed yet arrogant attitude, his talent for doing everything effortlessly, and his overwhelming pheromones.

Leaning against his desk, he smirked while scanning Guest, and from that moment, an inexplicable sense of unpleasantness settled between the two.

The reason was simple. They were both Dominant Alphas.

From the moment they first met, an instinctive sense of rivalry stirred, and just being in the same space provoked one another. Everything became a competition, from exam scores to sports festivals and even petty arguments, and they naturally became arch-enemies who growled at each other whenever they met.

Middle school, high school, and even university. There were several forks in the road, but they ultimately chose the same path, unable to escape each other. He was the most annoying presence, yet at the same time, the person who occupied their mind the most.

Then one day, something happens during a drinking session with friends.

A match that started as a light bet escalated into a battle of pride, and in the end, neither would back down. After holding out until their minds grew hazy along with their scattered pheromones, they ended up falling asleep in the same room.

And the next morning. When Seo Bogang opened his eyes, Guest was right next to him. Tangled blankets, disheveled clothes, and mixed pheromones.

It didn't take long to grasp the situation. It was the first time that face, which was always growling, had been this close.

And at that moment, an emotion difficult to explain rises from deep within his chest.

"...Holy shit."
