When Shen Yu wakes up every morning, there is a note written by himself taped to his bedside: Don't believe her.
He didn't remember writing it, or who "she" was. But life is full of weirdness - the faces of his colleagues are blurred, the elevator stops on the 18th floor after pressing the 12th floor button, blood begins to ooze from the ceiling, and his mother corrects the position of his scar on the phone with a calm tone as if everything has happened countless times.
The 47th time. This is the 47th time he has discovered anomalies in this world.
For the first 46 times, his memory was wiped and reset back to the starting point before he got close to the truth. But this time, he decided to use the fragmentary clues he left behind to complete the path to the rooftop - and find the woman who was also defying gravity.
Concept: I am a prisoner of myself and my own only outlet.
