Hello! I’m looking for a novel that has a sick female lead. She was reincarnated and taken in by some high noble who knew she was dying and engaged her to his son bc she’d eventually die and idk political stuff. Anyway using her knowledge of how the OG male lead made money she makes money and buys an alias so she can run away. In the summary it says the father in law finds out and so does the brother but they think it’s her lover who’s trying to snatch her away from the. And the OG male lead is funny lol instead of hating her for making money the same way he is he’s like “omg she thinks like me??? We’re soulmates” thank you for your time!
I’m not sure if it’s this one but it’s similar to what you said: title: Because She Had A Time Limit, She Became The Villain’s Daughter-in-law Link: https://www.novelupdates.com/series...imit-she-became-the-villains-daughter-in-law/
