My Secret, Terrius – Do You Need a Babysitter?

“My Secret, Terrius” is a 2018 Korean drama series, with 32 episodes, and categorized as Spy Thriller, Family, Romance, and Comedy (Rom-Com).

SUMMARY: A woman’s husband is murdered and a secret agent who happens to be her neighbor, volunteers to babysit her kids because she does not know she and her kids are also in danger.

♦ I’m Not a Spy, I’m a Mom

In “My Secret, Terrius”, a clueless innocent woman is dragged into the ruthless undercover world of espionage loaded with good and bad spies, spying on her and each other, and engaging in all sorts of cloak-and-dagger activities. Go Ae-Rin got married and had adorable twins, a boy and a girl. Her husband is the full-time breadwinner and she does whatever she can to make money and help pay the bills. One day her husband died. It was so sudden.

Yes. When someone murders you, it’s usually sudden. But she did not know her husband had been murdered. Go Ae-Rin thought her husband died because he had a heart condition. Even so, his unexpected death was quite a shock! She now had to fully financially support her family. Before her husband died he interviewed for a job as a secretary but was rejected. Since she did not get a full-time job, she worked various part-time jobs to make ends meet.

Why Did Go Ae-Rin’s Husband Die?

It all happened so fast. Go Ae-Rin and her husband argued and he wanted to make up. He went to get a nice gift and on his way home he witnessed a murder. He did not know the man being killed or the killer, but he had seen too much. Just like that … he had opened the door to undercover spying and he saw a bad spy doing something very bad!

He tried to escape and thought he had gotten home safely. But this was a trained killer who tracked him down and killed him instantly. Go Ae-Rin’s husband had witnessed the murder of a top government official in charge of national security. He had also seen the face of the killer. This is why he had to die. There can’t be any witnesses.

  • Go Ae-Rin does not know about any this happened and so she had no reason to suspect foul play regarding her husband’s death. She also does not realize that now she and her children are in danger.

  • Go Ae-Rin rarely spoke to or interacted with her neighbor whom she called “Mr. 803”, so the thought probably never occurred to her that he was a spy, code-named “Terrius” AND he was wanted.

The National Intelligence Service has been searching for Terrius but he dropped off the grid. He is suspected of being a mole and having something to do with the disappearance of a nuclear scientist from North Korea. Terrius had been lying low while trying to find out who the real mole was, where the scientist was, and hopefully clear the “black mark” off his record as he is a loyal government agent.

♦ What Does Terrius Know?

“Mr. 803”, Kim Bon, CodeName: Terrius, also does not know his neighbor’s husband died or why he died. He does know that someone called “The Magician” (the bad spy) is back on the radar and he has been trying to track his movements. When he heard the news report that a top government official in charge of national security had died, he suspected it was the work of “The Magician”. According to the news, the government official died because of a heart condition.

Terrius decided to attend the memorial services for the government official, but while he was there, he noticed another funeral and saw his neighbor crying. That was when he realized her husband had died. However, he did not make a connection between the death of the government official and the death of Go Ae-Rin’s husband.

Go Ae-Rin’s children were at a park playing while she was attending her husband’s memorial services. They think their dad is on a business trip. The killer showed up at a park and tried to abduct the two children. Terrius was in the area and overheard the adults alerting each other about the missing children. He got close to a woman on the phone and tried to glean some information.

Someone had taken a picture of a man with the two missing children. He asked if he could see and recognized that the man who had taken the children was “The Magician”. WHY? Terrius is bewildered. His mind is filling up with all kinds of questions. But the main question is: What’s the connection? Why is “The Magician” after those children? Is he after the woman too? WHY?

Do You Need a Babysitter?

Terrius is clueless, but not nearly as clueless as Go Ae-Rin. He knows enough to know that Go Ae-Rin and her children are in danger. He’ll figure out why later. Right now he has to keep them safe from “The Magician”. Go Ae-Rin got a callback and was offered the secretary job at the company that had rejected her. If she is going to work full-time she will need a babysitter.

Terrius volunteers for the job. He made up an excuse telling Go Ae-Rin he needed money and she needed someone to look after her kids. It was a win-win proposition. After her friends vetted him and approved saying that he was probably competent and would be able to look after her kids, Go Ae-Rin hired him.

And just like that … Kim Bon (Code-name: Terrius), one of the country’s top secret agents, became a full-time babysitter/bodyguard. “The Magician” won’t be doing any disappearing tricks as long as he’s around.

The way “My Secret, Terrius” blends multiple genres like spy thriller, family drama, and rom-com sounds ambitious, but it seems like they pulled it off seamlessly. I’m fascinated by how Kim Bon’s character is a secret agent babysitting two kids while investigating a dangerous killer. It’s a scenario that could easily feel absurd, yet the ratings suggest it works beautifully. I’m curious how the show balances the tension of espionage with the lightheartedness of babysitting. A spy babysitter might seem implausible, but it offers a refreshing twist to both the spy and family drama genres.

I find Go Ae-Rin’s situation incredibly touching. Losing her husband and then unknowingly being thrown into danger with her kids is terrifying. She’s trying to piece her life together while completely unaware of the web of espionage she’s caught in. Her reliance on Kim Bon, someone she barely knows, shows her desperation and trust in others despite her loss. It feels relatable and heart-wrenching at the same time. I’d watch this just to root for her and her kids to find safety and some peace.

Gurls, I can’t help but question some of the story elements. For instance, wouldn’t it raise eyebrows for someone as high-profile as Kim Bon to take on a babysitting gig? It feels like a contrived way to keep him close to the family. I’m not saying it ruins the story, but it does stretch plausibility. That said, I can see how the emotional depth and humor might overshadow such details for most viewers.

The comedic angle of a serious spy juggling babysitting duties is what appeals to me most. I imagine scenes where Kim Bon uses his training to change diapers or fend off suspicious neighbors while staying undercover. It’s a goldmine for situational comedy, and if done well, it must be a riot. I’m sure his interactions with the kids add a lot of heart to the humor, too. It sounds like the perfect feel-good show after a long da

Like the Concept of spy protecting innocent lives while solving a murder mystery is classic action-thriller material. Throwing in “The Magician” as a villain adds a mysterious, almost mythical element that makes the stakes feel even higher. I’d watch this for the intense sequences where Kim Bon faces off against seasoned killers while trying to keep the kids safe. The spy-action aspect is what excites me the most.

The romance angle between Kim Bon and Go Ae-Rin seems subtle but promising. I enjoy stories where love develops in unexpected circumstances. Watching them navigate danger and their growing connection, especially with her kids in the mix, must make for tender and heartfelt moments. I’m glad it doesn’t seem overly forced, as that would detract from the story’s other strengths.

The setup of “My Secret, Terrius” is definitely unique, but I wonder how realistic it is for someone like Kim Bon to evade the National Intelligence Service while actively intervening in Go Ae-Rin’s life. Wouldn’t taking on such a visible role as a babysitter risk exposing him? It’s a bold storytelling choice, but I’d have to suspend a lot of disbelief to enjoy this. Maybe the character dynamics and plot twists make up for it.

The spy calls the mother “scatter-brained”. She's not really. It's just that she doesn't know she is dealing with dangerous people. She's innocent and has no fear because she doesn't know she's supposed to be scared. The spy always has a serious face but you can tell when it comes to the kids, he's a softie. The episodes are short but packed with comedy and suspense.

Terrius seems to be able to make himself invisible to the people that he doesn't want to see him. Even when they think they can catch him, he manages to lose them and disappear. However, Go Ae-Rin and her friends see him doing things but they don't know how to connect the dots. It's realistic in that the average person never stops to think that the cool quiet guy who lives in the neighborhood and who you see at the park and the grocery store is a spy! Spies look like ordinary people.
