Su Ran, a minor actor who barely registers in the entertainment industry, discovers that the Empire has forcibly assigned him a partner, and that partner is a female slave.
All because he's an inferior male bug whose level was assessed as F.
Su Ran: "I never signed up for the matching program."
Manager: "I signed you up. You need a powerful female bug to protect you."
Su Ran: "Are you sure I can handle a B-rank female bug?"
Manager: "I believe your charm is irresistible."
Su Ran: "Get lost!"
Rong Xu, a commoner major general, loses a competition for a high-ranking male bug against a noble female bug, is framed, and becomes a female slave.
When his name appears on the compulsory matching list, the Star Network erupts.
Subordinate: "Major General, please don't worry. We've already found the most suitable match for you."
Rong Xu: "An F-rank male bug? That's as rare as an S-rank one."
Subordinate: "But he has no power or influence, so he'll be easy to handle."
Rong Xu: "Fine, that'll do."
At first, the newlyweds have no expectations for married life.
Until one day, Rong Xu sees a male bug take down an alien beast single-handedly.
Su Ran: "Oh dear, I can't keep my secret identity hidden anymore."
Rong Xu: An F-rank male bug? Are you kidding me?
Su Ran: "What, don't you recognize your own male master anymore?"
Rong Xu: I can't believe I don't recognize my own male master...
