Watch Out! The Genius Heiress — Episode 3

After growing up in the countryside, 21-year-old Isabella Patton returns to her wealthy family. She soon meets the handsome (and much older) Oliver Bates, who begins to pursue her relentlessly, unaware that she is his fiancée. Meanwhile, Isabella's cousin, Eliza, who was raised by the Patton family in her place, desperately tries to turn the entire family against her. Unfortunately for Eliza, Isabella is a genius specialist with unparalleled talent in medicine and technology, outsmarting Eliza at every turn. As Isabella's unique skills are revealed, she wins the support of her five brothers and parents, becoming the jewel of the Patton family, while remaining just out of Oliver's reach.
