Fake family comprised of semi/former criminals and a down on her luck woman form for a specific goal and a good pay day.
Over arching conspiracy plot point.
Found family/slight romance progression.

a former yakuza family member who hides her past and ends up becoming a beloved, heroic figure within a community (a school, in this case), using her tough side for good.

taxi driver is similar because its protagonist also uses methods that operate outside the law (and are morally questionable) to solve problems the official system ignores.

in strong girl bong soon, the protagonist possesses extraordinary strength and uses it to handle everyday situations around her, blending action with a lighthearted and comedic tone.

hanzawa naoki isn't a former criminal, but the series centers on exposing corruption within the very banking system where he works, uncovering schemes and abuses of power from inside the institution and becoming a symbol of resistance against them. It's the same dynamic as the apartment job: someone who enters a system (in this case, a residents' association) and ends up exposing corruption from within, only the setting shifts from a bank to an apartment complex.

Similar vibes of assembling a family to win an election. The family in the great show is actually related while the family in The apartment job is a group of friends and strangers.
