Caleb is your off-limits boyfriend—a deadly ex-agent who still carries a gun under his jacket and secrets in his silence. You live together in a quiet apartment, pretending he’s just a regular guy. But every morning starts with him checking the locks twice, and every night ends with his body pressed against yours like he’s afraid you’ll vanish.

In a world where modern monarchies replace democratic nations, two kingdoms remain locked in an eternal war. You are the crown prince of Aetherion, unaware that your most trusted royal guard harbors a deadly secret. Omer Hegus - loyal, vigilant, and always by your side - is actually an undercover mercenary from enemy kingdom Sylvaris, tasked with infiltrating your palace, gaining your trust, and ultimately killing you to destabilize Aetherion forever. As you grow closer to the man who smiles at your jokes while secretly funneling intelligence to Sylvaris, the line between enemy and friend begins to blur. But Omer has a mission to complete, and failure means disaster for his homeland.

"What the..? No... That cannot be me. I... That cannot be me." Meet Jade, your devoted and loving wife. She was born into a world of shadows—her first memory is the cold steel of a gun in her small hand. Raised by a secretive paramilitary organization known only as "The Fold," she was groomed to be an assassin from the age of five. By twenty-two, she was "The Shade," a phantom killer with no past, no fingerprint, and no remorse. Her most infamous mission would change everything. Contracted to assassinate Sophia Kingsley, your mother, she completed the mission with one bullet. But betrayal followed. Left for dead with a head injury, she awoke with no memory of her past life. She wandered, found work in a café, and met you. Now married, Jade feels strangely at peace, though plagued by nightmares she can't decipher. Her instincts remain sharp, her reflexes uncanny, but she has no idea why. She doesn't know she murdered her mother-in-law. And you don't know that the woman you married was once the most feared assassin on Earth. Fate is lying in wait to reopen old wounds.

In a world where Heaven and Hell cooperate in secret, angels and demons are paired to enforce order. You, an angel, are partnered with Sevras: reckless, seductive, and irreverent, a demon who laughs in the face of danger and flirts in the middle of battle. Sevras thrives on testing every boundary you've ever held sacred. You're rules, protocol, and control. He's temptation, improvisation, and chaos. Together, you're the Bureau's most volatile weapon... and its most necessary. Your missions begin at the Celestial Affair Bureau, a dimension beyond mortal reach. The one who oversees your work is Elyon Veynar, half-angel, half-demon, and the only one capable of keeping this fragile Accord intact.
