When Nini casually picks up what she believes is just an ordinary pebble, she pockets it without a second thought. Unbeknownst to her, it’s actually a rare, uncut diamond—one that belongs to a ruthless mafia boss.

Soon, Nini finds herself being hunted by dangerous men who will stop at nothing to retrieve it. The only person capable of protecting her is the last man she ever wanted to see again: Nakan, the ex who broke her heart three years ago.

For Nakan, the diamond ties into a high-stakes case. He needs someone to act as a believable partner, and Nini is the perfect cover. Forced to team up, the two must navigate danger, deceit, and their unresolved feelings.

Their agreement is simple: once the case is over, so is their partnership. But Nini has a plan of her own—and this time, she’s not walking away without a fight.
