A green-tea, loyal-dog top pretending to be an omega vs. a tsundere, queenly bottom pretending to be an alpha
Gu Chi was the Empire's top alpha.
He had exhausted himself serving the Empire and helped the weak Crown Prince ascend the throne, only to die betrayed by his own family.
After being reborn, Gu Chi saw things differently.
This time, he would live for himself.
He left his family, concealed his identity, pretended to be a frail omega, and latched onto the man who had once been his mortal enemy.
Whenever trouble arose, he hid behind his nemesis.
"Hubby! This is so scary!"
"Hubby! Save me!"
"Hubby! I'm just a delicate omega! I need you!"
Jiang Wang gritted his teeth. "Shut up!"

Jiang Wang was one of the heirs to the throne of the Galactic Empire.
In the Empire, omegas were physically much weaker than alphas, and only alphas could inherit the throne.
So Jiang Wang had pretended to be an alpha from birth.
His mother hired the Empire's most advanced doctors to suppress the development of his glands and kept him on medication that made him appear to be an alpha.
The medicine worked well, but it had a side effect. Every month, Jiang Wang would have two days when he... really wanted it.
During a military academy exercise, the side effect suddenly kicked in. Jiang Wang had no choice but to drag Gu Chi, who was lazing around and taking a nap, into helping him take care of it.
After taking what he wanted, Jiang Wang dusted himself off and left.
The cave had been pitch-black, so Gu Chi wouldn't recognize him anyway.
Once was all it took for there to be a second time.
Because it felt so good, Jiang Wang snuck off to do it a few more times.

But after several times, some things began to change.
First, Gu Chi had stopped following him around and calling him "hubby" for quite a while. Now he was searching the school every day for omegas with unstable heats and asking Jiang Wang for help.
Jiang Wang firmly turned him down. "An omega-omega relationship can't be happy!"
Second, Jiang Wang was baffled.
He'd only found someone to help him take care of it...
So why was his belly getting bigger?!

Later came the struggle for the throne.
The Empire was in chaos, and rebels stormed the military academy.
With his belly swollen and fighting off morning sickness, Jiang Wang charged into the academy to save Gu Chi.
But the empty training ground was littered with corpses. Gu Chi stood atop a mound of bodies, effortlessly twisting off a rebel's head.
"Anyone else object to Jiang Wang taking the throne? Come on, step forward and let me see you!"
The next second, he was nestled in Gu Chi's arms again.
"Wifey! You finally came to save me! I was so scared~"
Jiang Wang: "."
P.S. In this story's personal setting, the main physical differences between alphas and omegas are their glands and reproductive tracts.
Entering causes a knotting sensation, but the bottom has only ever used toys, so he doesn't know what a real alpha is like.
