In her previous life, the heroine was heir to a reclusive medical clan. She trusted a two-faced man and her stepsister, who stole the family's secret manual and caused her parents' deaths. She too died in a fire, only discovering before she died that she was pregnant with the man's child. Reborn at eighteen, she finds herself on the day before her stepsister's scheme would ruin her reputation and force her into an arranged marriage. She is already carrying the future “genius darling baby” in her womb.
