The Sword Venerable Teaches You How to Disguise a Dominant Alpha as a Sweet Omega

Sword Venerable Transmigrates into an ABO World:

One punch takes down three Alphas?

You saw that wrong! That did not happen!

I'm really just a weak little Omega~

A gorgeous beauty who only wants an ordinary life, with MAX combat power, an Alpha pretending to be an Omega, gong vs.

A strong Alpha who only wants to protect his gong, but ends up not only being protected by his "weak little Omega" but also getting topped by him, a devoted puppy-like shou

Bonus scene:

Their first meeting

Shou: "You Alphas are ganging up on an Omega!"

He turns around: "Are you okay?"

Gong (quickly pulling his hand back): Who's this? Good thing he didn't see through me.

Later

Shou: "Um... If you don't mind, could I protect you?"

Gong (You're decent, both in character and in combat. I guess you can stay), nods.

Shou (overjoyed, dancing around), secretly adds the words "for the rest of our lives" in his heart.

Then later

Shou (eyes blazing): "Why do you have an Alpha's pheromones on you?!"

Gong (it's actually his own pheromones, and he's figuring out how to bluff his way through): "Well..."

Shou (devastated): "Did another Alpha mark you?!"

Gong (=.= at a loss for words): "...If you say so."

Shou (heartbroken): "You have an Alpha now...?"

Then immediately indignant again: "Who was it?! Tell me! I-I... If he dares treat you badly, I'll make him pay!!!"

Gong (laughing inside): This is so much fun. Let's tease him a little more~
