妹よ、もう遅い。~絶縁からの下克上~

"Tech mogul Daniel Lewis was poisoned by his sister Emily and her boyfriend Jason, only to be reborn at the critical moment of his father's terminal illness and the impending inheritance division. Facing his equally reborn, power-hungry sister Emily, he deliberately ceded control of Lewis Innovations—riddled with financial loopholes—taking only his father's entrepreneurial journal. Using insights from the journal and memories from his past life, Daniel traded stocks to raise seed capital, rapidly growing Cosmos Technologies and catching the attention of investment queen Diana Sterling, who soon became a key partner. Meanwhile, Emily struggled to steer Lewis Innovations toward success. After stealing Daniel’s plans for The Everest Project, she fell right into his trap. Through clashes at tech expos and financing meetings, Daniel outmaneuvered her at every turn, igniting a high-stakes battle over family assets, cutting-edge projects, and long-simmering revenge."
