The Virtuous Omega Disguised as the Vicious Colonel

Colonel K is a legend of the Omar Empire. He single-handedly destroyed the Star Pirates Warship, with mercilessness and cruelty, and everybody trembled at the mention of him. Lan Yu, dignified and elegant, the model of thousands of Omegas, mistakenly became the black-hearted Colonel K.
In order to keep the persona from falling apart, from then on he punches the intergalactic beasts and kicks the bandits’ out of their nests, tore a mecha to pieces with his bare hands, and the corners of his lips picked up in a cold smile. As an Omega who is thinking about getting a husband and having a child, Lan Yu feels like he’s suffocating.
But the good thing is that he was once a movie star, with his amazing acting skills, no one noticed any difference between him and Colonel K, whose name was used to stop children from crying.
Except for his nasty rival, Lu RanKong.
Lu RanKong could always find the “Interstellar Butcher” Colonel K’s unnoticeable changes.
With the corpses of Star Pirates under his feet, the ion gun leaning on his shoulder, his hand on his hand-knitted woolen holster. With the wind still in his face, a corner of his uniform’s shirt lifted, showing an embroidered yellow flower. With skin scuffed fingers, a grim, bloodthirsty smile, his eyes filled with tears.
At night, he would only fall asleep if he was holding a teddy bear? He drank the nutritional supplements with no expression, but the bottle was labeled with ‘orange’ and ‘mango’ flavors.
Lu RanKong slightly narrowed his eyes. Why did this black-hearted K become more and more like a ♥ K?
Yet he found the other man f*cking attractive!
