Since there is no review, I guess I will take my limited time to be the first to write about what I think is a great show. This is my second Hong Kong drama to watch. Someone mentioned it's similar to Madam Cutie on Duty which I dropped, just because the English subtitle is right on top of the Chinese subtitle makes it hard to read. Anyways, I am not familiar at all with the cast, so seeing new faces is refreshing to me. The Female Lead Samantha Ko is so pretty, either she is in the agent mode or the housewife mode.

WARNING: MILD SPOILERS AHEAD!!! THOUGH NOT THE MAIN PLOT AND ENDING

So the story is about Samantha Ko playing as the secret agent C9, whose private organization she worked at is to protect VIP people both native and foreigners while they are in Hong Kong. Alas, the organization is annihilated by a terrorist group Black Hole and everyone dies but her. An orphaned who was adopted by the organization since little, of course she was lost without any family member until she met a market veggie seller King (played by Kenneth Ma) and his family. So she started a new life as a housewife with nickname Cute Mom.
At first, I was really pissed that she took a role as a doormat. So different than her badass role as C9. She basically devotes her life helping her husband selling veggies in the market AND also taking care of her in-laws. Everyone seems depend on her, and she doesn't even complain and stays cheerful. I personally am annoyed with her looser brother-in-law and annoying sister-in-law.
Thankfully, the story soon becomes interesting when apparently there is another survivor of the secret organization: agent B3, who was a partner of C9. Upon knowing that C9 is alive, B3 contacted her and asked her to team up with him again to avenge the death of their brothers and sisters. C9 agreed, and soon we watch several episodes of some hilarious some heartbreaking scenes of C9 juggling between her secret mission and her household chores. The story becomes more interesting when we find out there are a few more ex members who are actually still alive.
By the middle of the drama, the story becomes somewhat melo when King finds out that Cute Mom is actually a secret agent, thanks to B3 who purposely makes it so. King was pissed because his wife has lied all way through since the beginning, and Cute Mom cannot bear seeing the family may become a target by Black Hole. So they are separated, and others only know the couple had a huge fight and Cute Mom left. The funny thing for me that now the family members scramble trying to do house chores Cute Mom did all in the past.
We then see the Female Lead being badass again as C9, although the drama is realistic enough showing her worrying and missing family make her did a few physical and mental mistakes during re-entry as an agent. I will not spoil you how the drama ends, but the plot twists are actually surprising and interesting, makes this rare Hong Kong gem fun to watch.
In conclusion, the story is great, especially the action scenes, cute romantic scenes, and family-get-together scenes. You can skip the side stories/couples, I think they're just fillers. The acting is also great, especially the fighting actions and the great chemistry between Samantha Ko and Kenneth Ma, and I also like the father in law and the step son. The OST is good, "Learning to Love" by Kayee Tam, you can get the OST link in my custom 2020 Completed Drama list if you want. Great re-watch value since it was only 20 episodes with 45 minutes duration, just skipped the draggy side stories parts.
