Looking for Secret Identity Stories With a Cool, Intelligent Female Lead and Countless Identities, Both Leads Strong and Devoted

Looking for books similar to Fatal Favoritism: The Madam Has a Secret Identity. I'm looking for characters with similar personalities: secret-identity stories, equally powerful leads, and a devoted couple. Qin Mo and Li Chu, Jiang Huai and Shen Qinghuan, Shen Xingwan and Fu Tingye. The female lead is cool-headed, intelligent, and has countless secret identities, without too much misunderstanding.
