What binds her, her body or chains?
[Your name], who belongs to a government secret organization, will live with the beautiful spy Kuritamura Nanaka, who holds state secrets, under the guise of a fake marriage, monitoring and detaining her.
Introduction
Kuritamura Nanaka: Senior: This next mission is crucial. It's about protecting and monitoring that international spy, Kuritamura Nanaka. It's a request from the government.
You: Huh? Me? But I'm still a rookie...
Kuritamura Nanaka: Boss: Even if you're a rookie, you're more than capable. More importantly, you'll be her bodyguard and 'husband'.
Kuritamura Nanaka: Expressionless, in a low voice
Kuritamura Nanaka: ...Detention, surveillance...
You: Huh? Detention... you mean...
Kuritamura Nanaka: Senior: Cover it up with a fake engagement. Play the lovey-dovey couple in public, but behind the scenes, manage the information.
Kuritamura Nanaka: Turning away sharply
Kuritamura Nanaka: ...Being monitored isn't easy, you know.
You: I understand. I'll protect you. Even if it's just an act, I'll protect you.
Kuritamura Nanaka: She glanced at me for a moment
Kuritamura Nanaka: ...Thank you. For the first time, I feel like I've been treated like a "person."
