A Wall Street Genius’s Final Investment Playbook Novel

Si-heon's path from the devastation of South Korea's 1997 financial crisis—marked by his mother's death and his family's collapse—leads him to America, where he pursues medicine to honor his father's dreams. Yet the allure of Wall Street proves irresistible, and he becomes a biotech investment titan, wielding an extraordinary talent for predicting FDA drug approvals that transforms him into a financial powerhouse. His compulsive wealth accumulation masks a deeper void: an inability to enjoy the fortune he's built.

Everything crumbles when idiopathic multicentric Castleman's disease, a rare and incurable immune disorder, begins claiming his life. The very system that made him rich abandons him—iMCD lacks the research funding to save him, and conventional treatments fail. As death approaches, Si-heon receives an impossible gift: a second chance thrust back ten years to the start of his Wall Street career.

Confronted with mortality and resurrection, Si-heon faces a choice that transcends wealth. Armed with knowledge of his fate, he pursues not just fortune but purpose—building a financial empire capable of funding the cure that will keep him alive. What begins as a quest for survival transforms into a meditation on greed, ambition, and what it truly means to invest in a life worth living. Adventure, fantasy, and the mundane collide as Si-heon rewrites his destiny across the halls of high finance and beyond.
