After hundreds of millions of years of human history
The human body clock is bright at noon,
and In a natural state when the night is dark
It has evolved to function normally.
However, due to further accelerated evolution,
We got bright nights.
As a result, the light of the night makes the body clock get out of control,
It hurts our health and makes us mentally unstable.
This is the story of a woman who was possessed by a night ray.
