Not NIS agents but they're from cyber crime unit. Together they investigate cyber crime and fight against cyber crime/hackers/corruption.

Okay first of all, this movie is not about doppelganger swap places but it's about a soul who were supposed to crossover were given a second chance in life for a month.

Fl were send back to earth and needs to adapt a new life as a housewife and mom instead of being a top prosecutor. Her soul swap places with the housewife's soul who is currently in coma.

There's alot of chaos and mess happen and it's so hilarious watching fl try to adjust her new life as a wife and mom which she never experience before.

What i like about this movie is although there's a financial restraint, some conflict between husband and wife and their teenage daughter is at the rebellious stage, she try the best as she can and her husband always has her back no matter what.

This drama has a mature relationship, non toxic relationship, communication is the key, trust each other and never give up on each other. This drama also focus on the adults in their mid 30's.
Of course there's a up and down in their life/relationship just like any other kdrama but the different is their relationship is rock solid and instead went for a breakup just like other cliche drama, they brave the storm together and always supported each other.
