Knocking on the Neighbor's Door

Palace Intrigue + Household Intrigue + Medicine +爽 Female Lead

Looking for books similar to The Eldest Sister Dies Tragically! The Little Daoist Nun Returns Home from the Mountains and Turns the Imperial Capital Upside Down (Lan Zhuohua). The female lead is so satisfying: if someone crosses her, she fights back; if she doesn't like someone, she slaps them. Once she finds the killer, she kills them outright. The male lead is always backing her up as she avenges her older sister. No misunderstandings, no unattainable first love...
