It turns out that people can really lose everything overnight: a plane crash on New Year's Eve caused Han Bin, who was in a high position, to lose all his relatives. The grief-stricken Han Bin was in a car accident and fell into coma...
A year later, Han Bin woke up in the hospital and was told that he had been in a coma for a year, and he had no memory of this year.
However, in the days that followed, he began to have hallucinations one after another and received mysterious messages signed memory...
What exactly happened during this year?
Is the appearance of a series of mysterious characters a coincidence or a careful arrangement?
Is the constant turmoil a conspiracy to overwhelm the sky, or is it an attempt to awaken deeply buried memories?
