Colonel K is a legend of the Oma Empire. Single-handedly destroying pirate battleships, ruthless and brutal—his name alone sends shivers down spines. Lan Yu, elegant and poised, the epitome of an omega, accidentally transmigrates into the black-hearted Colonel K. To maintain his image, he punches interstellar beasts, kicks bandit hideouts, tears apart mechs, and curls his lips into a cold sneer. As an omega whose dreams revolve around homemaking, Lan Yu feels suffocated. But luckily, he was once an award-winning actor with extraordinary skills. No one notices the difference between him and the child-terrifying Colonel K. Except for his infuriating rival, Lu Rankong. Lu Rankong always spots the unnoticed changes in the "Interstellar Butcher," Colonel K. Standing atop pirate corpses, leaning on an ion gun wrapped in a handmade knit cover. Walking with his usual commanding presence, his uniform fluttering to reveal a shirt corner embroidered with a tiny yellow flower. Sucking on a scraped finger with a sinister, bloodthirsty smirk—yet tears glisten in his eyes. And does he really sleep hugging a stuffed bear at night? Drinking nutrient packs stone-faced, each bottle labeled with tiny tags: "orange," "mango." Lu Rankong narrows his eyes. This black-hearted K is starting to look more like a hearts K. And damn it, he’s becoming irresistibly attractive!
