In 2024, in a quiet residential area of Tokyo, there stood a solitary house.
Inside one of its rooms lay a secret known to no one.
The owner of this house was Hiroshi Sato, a well-known political figure and a significant player in the political world.
He had achieved numerous accomplishments and garnered widespread support from the public.
Yet behind his success was a secret beyond human understanding.
One night, Hiroshi secluded himself in his study, staring at an ancient door embedded in the wall.
This was the key to his success: the "Door of Time."
Hiroshi had discovered this door in the old mansion he acquired when he was still a young politician.
Beyond the door lay the past and the future, and Hiroshi used it to gather information that paved his way as a politician.
The first time he went through the door was when he faced a political crisis.
Seeking advice from his future self, Hiroshi fearfully opened the door and saw Japan thirty years into the future.
There, he witnessed the ideal Japan he had built.
"So, this is the ideal Japan I will create," he mused.
With advice from his future self, he overcame the crisis.
From that moment on, he made rapid strides in the political arena.
The power of the door was immense.
However, it came with a great price.
Every time he altered the country's fate, his memories became shrouded in a fog-like haze.
As a result, his relationships with family and friends became strained.
Moreover, he began to worry that his meddling might be having some unknown impact on society as a whole.
Each time he interfered with the past or future, subtle changes could trigger unforeseen problems.
One day, Hiroshi discovered that Japan's future was in unprecedented turmoil.
Where had the ideal Japan he was supposed to have built gone?
Unexpected forces had risen, and society was in a state of disarray.
Moreover, in that chaotic Japan, he himself was nowhere to be found.
Determined to change this future, Hiroshi approached the "Door of Time" once more.
He had begun calling it the "Door of Time" around this period.
However, this mission was more dangerous than any before.
If he failed, his existence might be erased forever.
Thus, to change the future, he traveled to the past to meet his younger self, and together they devised a plan to avert the future crisis.
Not only did he collaborate with his younger self, but he also worked with former colleagues and rivals to launch new policies.
Upon returning to the present, Hiroshi was confident that his actions in the past had started to restore Japan's fate.
The future course for Japan was now secure.
There was no need to risk traveling to the future to confirm.
Japan regained its peace and prosperity.
However, the price was steep.
A significant blank remained in his memory, and eventually, he even forgot about the existence of the Door of Time.
More than ten years after forgetting about the Door of Time, Hiroshi reappeared from beyond the door.
The time had come to open the door once more.
When he opened the Door of Time, countless streams of time spread out before him.
Past, present, and future intertwined, revealing infinite possibilities.
The two Hiroshis sought a point within this vast expanse to reclaim part of their memories.
They chose an event from Hiroshi's youth, before he became a politician.
2000, Tokyo
A young Hiroshi, still a university student, was about to experience the event that would inspire him to pursue a career in politics.
To be continued.
