Katana Hill is the daughter of a tycoon businessman, but she developed amnesia due to an accident committed by her father’s opponent. A poor woman adopted her with her two children, and they called Katana Hill “mother,” and it didn’t take long for Katana Hill to consider them a family. One day, the mother who took care of Katana Hill got sick, and Katana Hill decided to work for her, and she accepted all the honorable jobs that were offered to Katana Hill. One day, Katana Hill was looking for a job, and she was found as the maid of a tycoon businessman named Caliber Cuhen. They knew Caliber Cuhen was just a businessman, but he had a dirty little secret: he was a Mafia boss. When Caliber Cuhen saw Katana Hill, he was immediately fascinated by the woman’s beauty, and he tried to avoid her because she had two children. Katana Hill asked Caliber Cuhen for financial help to pay for her mother’s heart surgery. Caliber Cuhen immediately gave in to her, but with a condition: she would become a sex slave. At first, Katana Hill didn’t like it, but she didn’t have a choice but to accept it. Caliber Cuhen fell even more in love with Katana Hill when she found out that Katana was a virgin and she just claimed to be the mother of the children because the children wanted to have two mothers. One day, Caliber Cuhen found out that Katana Hill’s family killed his parents, and since Caliber Cuhen did not know that Katana Hill was pregnant with his first son, whose name was Bullet, he left Katana Hill. But later on, he regrets it. When he finds out that Katana Hill has a son and his father, he immediately does everything to bring Katana Hill back with him, and so did his son, Bullet.
