300日徹夜で作ったシステムの成果を奪われ、1000万円のボーナスをゼロにされた私。翌朝、祖父の遺した謎の口座に1億円が振り込まれた瞬間、上司と裏切った彼氏の人生は完全に崩れ落ちた…

The year-end party. On the stage, in front of all the employees, my year's hard work was crushed in an instant. I had spent over 300 days holed up in the lab, pulling countless sleepless nights, single-handedly completing a risk management system. My boss stole the credit for this achievement, which had contributed to both the company's sales and stock price. And the 10 million yen special bonus I was supposed to receive was confiscated entirely. All I received was a mere 40,000 yen in consolation money. Furthermore, my boyfriend, who had supported me for three years, instead of protecting me, flattered my boss and said: "My promotion depends on this. Just give up the 10 million yen." I didn't cry. I didn't scream. I simply left the venue quietly. But the next morning, the moment I opened the mysterious trust account my grandfather had left me, my life changed completely. The amount deposited: 100 million yen. The 10 million yen that was supposed to have been stolen from me returned to me ten times over. And with all the evidence—development logs, time cards, accounting records, falsified reports—I headed to the chairman's office. My boss who stole my achievements. My boyfriend who tried to use me as a stepping stone for his own promotion. The employees who laughed at me just yesterday. The moment all the truth was revealed, the blood drained from their faces. A woman who had 10 million yen stolen turns everything upside down with 100 million yen and her own abilities. Who had the last laugh...?
