SYNOPSIS

Won Ryu-hwan has been a soldier in the North Korean Army’s elite 5446 Corps since the age of thirteen. After nine years of brutal training, he becomes a perfected killing machine, excelling above all others—including his greatest rival, Rhee Hae-rang, the son of Rhee Moo-hyuk, a high-ranking officer and the founder of the 5446 Corps. The unit’s mission is absolute: the unification of Korea. One day, Won Ryu-hwan is ordered to infiltrate South Korea as a spy.

Two years later, living under the alias Dong-gu, Won disguises himself as a mentally slow village idiot in a poor South Korean neighborhood. He works and lives in a small grocery store run by Soon-im, wearing the same loose green tracksuit every day. To maintain his cover, he deliberately makes mistakes at even the simplest tasks, such as sweeping the street. Soon-im pays him a meager monthly wage of 200,000 won and feeds him miyeok-guk (seaweed soup) every day. Her son, a police officer, constantly complains about the food and argues with his mother.

One day, Won notices a familiar presence near the grocery store—Rhee Hae-rang. The two clash in a fierce fight that reveals their true identities. Rhee Hae-rang, also sent south on a mission, is disguised as an aspiring rock musician who repeatedly fails auditions, clinging to a fragile dream of reinvention.

Soon after, another agent appears: Rhee Hae-jin, a seventeen-year-old soldier from the same corps, sent south disguised as a high school student. Born into poverty, Hae-jin joined the army as his only means of survival and social mobility. He idolizes Won Ryu-hwan, whom he sees as the embodiment of strength and purpose.

As time passes, Won learns that Soon-im is seriously ill. Her condition reminds him of the mother he left behind in the North. Deeply moved by his concern, Soon-im asks what he would like to eat. Won hesitates, then asks for miyeok-guk with beef—a dish traditionally associated with care and birthdays. Though tired of cooking it, and despite her son’s hatred of the meal, Soon-im prepares it for him.

Rhee Hae-rang and Rhee Hae-jin later visit the grocery store, where Soon-im warmly welcomes them and offers to make samgyetang (ginseng chicken soup). The three men help her with chores, laughing together like a family. In a quiet moment, Hae-jin asks Won what he would want to be if he were born again. Won answers simply: he wants to live an ordinary life.

That fragile peace is shattered when local thugs come to the store demanding alcohol supplies. When Soon-im refuses, they brutally assault her. That night, her son attempts to confront the gang alone but is severely beaten and left unconscious. In response, Won, Rhee Hae-rang, and Rhee Hae-jin storm the gang’s hideout. When Hae-jin calmly asks whether they should kill the men, Won stops him, ordering instead that they cripple them—enough to ensure they will never harm Soon-im again.

Meanwhile, political tides shift in the North. Following an agreement with the South, North Korea agrees to hand over the identities of thirty high-ranking spies. Colonel Kim Tae-won proposes allowing the agents to commit suicide instead. Rhee Moo-hyuk approves, and Kim travels south to oversee the final mission.

By then, only four agents remain alive: Won Ryu-hwan, Rhee Hae-rang, Rhee Hae-jin, and Seo Soo-hyuk—who is revealed to be a senior operative and team leader within South Korea’s National Intelligence Service.

Before the final confrontation, Won appears before Soon-im no longer as Dong-gu, but dressed in a black suit, speaking clearly and calmly. He urges her to undergo surgery before it is too late. Though she shows no shock at his transformation, Soon-im quietly hands him a bankbook—money she secretly saved for him over the years as his true wages, fearing he might otherwise squander it.

Won and his comrades meet Kim Tae-won in a warehouse. Won tells him he is willing to die, as long as his mother is kept safe. Kim offers no answer. As Kim moves to execute the three men, Seo Soo-hyuk arrives with NIS agents and reveals the truth: Won’s mother was executed the very day he joined the 5446 Corps.

Consumed by grief and rage, Won fights Kim and the soldiers. In the chaos, Rhee Hae-rang receives a message that he has finally passed an audition—just before he plunges from a balcony while grappling with Kim. The NIS retreats, leaving behind the lifeless body of Rhee Hae-jin.

Mortally wounded, Won collapses. In his final moments, he takes out the bankbook Soon-im gave him and holds it close as he dies. From afar, his voice echoes—his answer to Hae-jin’s question:

He wanted to live an ordinary life.


REVIEW

I wrote the synopsis of Secretly, Greatly immediately after the performance because I wanted to preserve the nuances of the scenes before memory softened them. The details mattered — the seaweed soup, the bankbook, the grocery store, the transformation in the black suit, the quiet look on Soon-im’s face. I did not want the emotional texture to blur with time.

But I could not write the review.

Not because I lacked thoughts. I could not write because I felt physically unwell for Won and the others. There was a heaviness that did not feel like ordinary post-show melancholy. It was closer to grief.

These were boys who entered military life at thirteen. They were trained into precision, discipline, and obedience before they had the chance to grow into flawed, ordinary young men. Their loyalty was not romantic. It was the only structure available to them. And when political tides shifted, they were not reassigned, not rehabilitated, not mourned. They were simply removed.

What unsettled me most was not the final betrayal.

It was the realization that Won had been orphaned at the very beginning — without ever knowing it. The day he entered the 5446 Corps was the day his mother was executed. His entire identity — his discipline, his excellence, his endurance — was built upon the belief that he was protecting her. He was not betrayed only at the end. He had been living inside a lie from the start.

And yet, in the middle of this machinery of disposal, the show places a grocery store.

At curtain call Soon-im mentioned that this was her first musical, coming from straight theatre. That fact made sense. She did not carry melodies; she carried gravity. She fed Dong-gu. She paid him — quietly saving his wages in a bankbook. She did not humiliate him, never exposed him. And when he appears before her no longer as the foolish Dong-gu but upright, composed, dressed in a clean black suit, she does not gasp or recoil. She calmly hands him the bankbook she has been keeping for him.

I never felt that she believed he was truly foolish. Her calmness suggested recognition.

If the entire show were reduced to one word, it might be “mother.”

Won’s biological mother is erased before he understands what he has lost. Soon-im becomes the only maternal presence he encounters — not sentimental, not dramatic, simply steady. During the curtain call, the cast turned toward her and saluted together. And it felt right.

The choreography throughout the show was strong — particularly in the training sequences. The ensemble work had an athletic sharpness reminiscent of Newsies — tight group turns, synchronized jumps, explosive floor coverage that emphasized collective discipline over individual flourish. Like Newsies, the movement vocabulary highlighted youth, physicality, and unity, but here it was redirected toward militarized precision rather than rebellious energy. The three-story steel structure that opened to form corridors and balconies reinforced that discipline visually, creating vertical tension — authority above, soldiers below, and finally confrontation suspended between levels.

Musically and physically, the production was solid. Won’s voice carried force in the tenor range yet could descend into baritone depth without strain — controlled, resonant, never pushed. Nothing distracted me technically. If someone had been weak, I would have noticed.

But the final battle was difficult for me.

The last confrontation extends into a long, knife-heavy sequence with repeated injuries and multiple casualties. Characters appear to fall, then rise again to continue fighting. For some, this may have intensified the emotional arc — clarifying who stands with whom, who sacrifices, who betrays. For me, it became agonizing.

I kept thinking that structurally the scene required only resolution: Kim Tae-won either dies or is captured. Seo Soo-hyuk carries a gun — apparently with only five bullets — and uses it at the end. I found myself wondering why he alone was visibly armed, why the NIS agents did not create clearer asymmetry, why the fight extended so long with knives when firearms were present. The repetition blurred inevitability. Instead of tightening the tragedy, it prolonged the suffering.

I almost wished for a theatrical interruption — a freeze, a suspended musical moment — something that would allow articulation instead of endurance.

Won’s death, especially, felt slow. Perhaps that was the point. To make us sit inside the cost. But I had already understood the cost when the truth about his mother was revealed. I did not need further physical agony to believe in his tragedy.

By the time he collapsed holding the bankbook, I was not crying. I was unsettled.
What hurt was not that they died. What hurt was that they had never been allowed to live.

They were not given the chance to accumulate small failures, selfish ambitions, ordinary boredom. Even their dreams were fragile — a rock audition passed moments before death, a simple wish to live normally in another life.

When Won answers that he wants to live an ordinary life, the line does not feel poetic. It feels unreachable. Perhaps that is why I could not write the review right away.

The show is framed as a thriller about espionage and national mission. But what lingered for me was something smaller and heavier: boys raised into soldiers, used efficiently, and disposed of cleanly — and the brief glimpse of mothering that arrived too late.

Sometimes analysis requires distance. That night, I only had ache.
