★One day, I started seeing green numbers flashing on people’s backs, indicating their lifespan.

Become a “viewer”
One day, Lee Won-yeong, an ordinary college student, loses his parents in a car accident. He almost dies but miraculously survives. When he wakes up in the hospital, he sees something strange: green numbers flashing on people’s backs. The numbers are visible only to him. As the day passes, the numbers decrease by one. Won-yeong learns that the back number indicates the days each person has left to live. If there’s a number 1 on one's back, then today’s the day one will die.
Like this, Won-yeong becomes a “viewer.”

Everybody will face “the day”
Everybody must face their last day of life. However, people live as if “the day” will never come since they don’t know when that will be. It is evident that everyone will face that at some point, but no one knows when that moment will be. However, Won-yeong now can tell when a person will die by looking at the number of their back. But ironically, he cannot know the number on his own back.

Someone without a number on their back
One day, Won-yeong sees a couple with the numbers on their backs flickering in red at a café. Won-yeong knows intuitively that there will be an accident that leads them to death, so he tries to save them from the immediate danger. Despite his efforts, they end up losing their lives in front of Won-yeong. Then a man without a back number approaches him. He warns Won-yeong not to intervene such as trying to prevent someone else’s death. Also he states that human intervention in life and death will cause worse trouble.

Finding another viewer
Won-yeong finds out the way to check his back number: finding another “viewer” like him. Won-yeong has a feeling that the man he saw on the day of the car accident may be the one. He takes an express bus to search for the man. When the bus stops at a rest area, he decided to use restroom. As he walks back toward the bus, Won-yeong witnesses a surprising scene: a man with number 1 flickering in red on his back sits in Won-yeong’s seat. Then the bus takes off right away.

Don’t want to know the number on my back
Won-yeong gives up trying to know his back number. There is nothing that would change even if he finds it out. There is nothing for him to intervene or to change, and no reason for doing so. He is determined to enjoy the freedom of “unknowing” to the utmost.
