The Genius Chaebol Firefighter

Choi Hee-soo was a genius and a third-generation chaebol heir. He was pursuing a PhD at MIT and had become the youngest person to complete Harvard's MBA program. However, he died from a pulmonary embolism caused by overwork. But an angel appeared and offered him another chance. "For every person you save from certain death, I'll give you one more day to live." Apparently, saving one person's life would allow him to live for one more day. His remaining lifespan was just one day. "I'm becoming a firefighter to save my own life, too!" #Survival #Hard Work #Genius #Overpowered Protagonist #Supporter #Professional
