Incase if you can’t get this movie this might be helpful!
At first, The Great Flood may not feel like a “bad” movie, but it can definitely feel confusing, especially if you’re used to traditional K-drama or Korean films with a clear emotional or linear storyline. This movie suddenly shifts tone and narrative, which can be disorienting. However, once you understand what the film is actually about, it becomes deeply meaningful and emotionally powerful.
The world in the movie is already ending. Humanity is almost extinct. The experiment exists because humans are trying to recreate humanity, not just biologically, but emotionally. They realize that without real emotions, especially love, the new humanity they create will never truly be human.
This is where An-na and Ja-in come in.
An-na is part of the Emotion Engine Experiment. She agrees to have her brain implanted into a simulation where she relives the same scenario again and again which is loop as y’all know.
Her role is to demonstrate genuine human emotion, particularly maternal love, because nothing is more raw or instinctive than a mother’s love for a child.
Ja-in, the child, is technically “just a subject.” She is supposed to abandon him. She is meant to choose logic over emotion. But she doesn’t. She loves him like a real child — and that is the entire point of the experiment.
An-na is tested to see if she can:
• Form real emotional attachment
• Make moral choices
• Choose love even when logic and rules tell her not to
She fails thousands of times.
The drawings scattered throughout the movie are not random. They represent past loops of the simulation. Each drawing shows Ja-in remembering her words: “I’ll be back. Wait for me.”
That’s why he keeps hiding in the closet every time. That’s why he keeps drawing the helicopter scene — and why the drawings slowly get better and more detailed. He remembers. He learns. He feels.
When An-na once tells him, “Draw me with some color,” the drawings begin to change. This proves emotional memory exists — even inside a simulation.
Her shirt changing numbers shows how many times she has repeated the loop. Each number represents another failure. Another reset. In total, she is trapped for 13,499 attempts, spanning around five years from her perspective (or even longer depending on interpretation). Some theories place it closer to 21,499 days, roughly 58 years, emphasizing the unimaginable emotional weight of the experiment.
The AI systems try to stop her ( mans with gun’s) They want to reset the simulation because the machine only activates when the subject reaches their version of emotional perfection. The world ends over and over because the simulation can run thousands of apocalyptic scenarios faster than real time.
The truth is:
An-na and Ja-in are already dead.
This is a machine using their memories to learn how human emotions work so it can create the next generation of “humans.”
In the end, An-na passes the test because she chooses love over logic.
Ja-in separating from her shows free will — something artificial intelligence cannot fake. When she is allowed to return to Earth, we see others who have also passed similar simulations. Humanity doesn’t survive because bodies are recreated — it survives because love was successfully learned.
The final message of the movie is clear:
Being human isn’t about being real or artificial.
It’s about love, memory, sacrifice, and the choices we make.
This movie isn’t confusing — it’s layered.
And once you understand it, it’s devastatingly beautiful. Also including few extra words I would say the experiment proves humans are defined not by survival instincts, but by who they choose to save, plus many of people have asked why “love” they would better come with something else but going deep down maternal love is used because it’s the hardest emotion to fake or replicate while AI can simulate logic endlessly, but love requires irrational sacrifice…
That’s it!!
