Watch Out! She's the Genius Heiress — Episode 5

After spending her childhood in the countryside, 21-year-old Isabella Patton returns to her wealthy family. Soon after, she crosses paths with the much older Oliver Bates, who pursues her relentlessly—completely unaware that she is actually his fiancée. Meanwhile, her cousin Eliza, who has lived in Isabella's place with the Pattons for years, tries to turn the family against her. However, Isabella is a medical and tech prodigy, effortlessly outshining Eliza at every turn. With each challenge she faces, Isabella proves her brilliance, slowly winning over her parents and five brothers. She quickly becomes the heart of the Patton family, but to Oliver, she remains tantalizingly out of reach.
