Under the shadows of the mafia / RM

"I'm not Kara!" Yumi shouted in frustration, pounding on the cold, reflective window of the interrogation room.

Across from her, the Mafia boss and his men watched in disbelief. "She's gone crazy in less than a month," he muttered, his voice cold and dismissive.

Yumi, a highly respected figure in both the intelligence community and the medical world, has always kept a low profile.

Her younger sister, Kara, on the other hand, has lived a life of recklessness and excess-always chasing the next thrill, and never hesitating to get involved with dangerous men.

But when Kara suddenly disappears after falling into the arms of the powerful Mafia boss Kim Namjoon, Yumi finds herself dragged into her sister's chaotic world. Mistaken for Kara, Yumi is taken captive by Namjoon, a man whose obsession with her sister knows no bounds.

As Yumi tries desperately to prove she's not the woman he's looking for, she begins to unravel dark secrets about her sister's involvement with Namjoon, and the price she paid for her reckless behavior.
