Beware of the Genius Heiress! — Episode 9

After growing up in the countryside, 21-year-old Isabella Patton is sent back to her wealthy biological family. Soon, she crosses paths with the charming (and much older) Oliver Bates, who begins to pursue her relentlessly—unaware that she is actually his fiancée. Meanwhile, her cousin Eliza, raised in Isabella's place by the Patton family, does everything to turn the clan against her. Unfortunately for Eliza, Isabella is an unparalleled prodigy in both the medical and technological fields, outsmarting her at every turn. Thanks to her unique talents, Isabella wins the support of her brothers and parents, becoming the crown jewel of the Patton family, all while constantly dodging Oliver's advances.
