Building Billions from My Second Chance - Episode 1

Chad wakes up confused but soon learns he must undergo a critical marrow transplant to survive. Despite not sharing blood ties, Chad reveals he has been living in Leon's place and refuses to harm him for his own survival. Tensions erupt as family members accuse Leon of stealing Chad’s achievements and living off their generosity, demanding he donate marrow to repay his debt. Leon resents being treated as a 'walking blood bank' and vows revenge if given another chance. The episode ends with Chad mysteriously reborn at age 16, forced to face the moment he originally signed the donation consent.
