At the last moment of life, if you could go back in time, would there be any regrets you want to make up for?

Dr. Carl and Dr. Menoria have a special job: they listen to people's wishes, travel back in time, and then turn those wishes into reality.

However, this also brings serious consequences. As determined by time, even the slightest change can cause irreversible disasters to reality.

Yet one proven fact is that if something has already happened, it can no longer be changed.

Provided that the wish is reasonable, this service is only offered to one kind of people - those who are dying.

This newly - developed technology can convert a person's spirit into an optical signal. With the help of the person's memory fragments, it can trace back step by step to the earliest time. Under one mystery and clue after another, it gradually uncovers the truth and realizes the wish... if everything goes smoothly...

This time, they came to the home of Nathaniel, an old man full of mysteries. Obviously, this job will be different from previous ones.

His last wish is... a door.
