Sengyou Shufu Tantei ~Watashi wa Shadow (2011)

Same female lead and the stories are similar. She plays a amateur detective who, on one hand, solves murder mysteries and on the other is just a normal P.I. Also, the romance is similar since both bosses end up falling for her.

about a powerless wife who regains her confidence through help of others

both are about how wives stand up and assert themselves with some comedy.
