lonely one-man play

In the winter of 2022, I retired from my job where I had been working for about 10 years.
Here are some of the reasons why I left that job:
1. I've been working diligently for about 10 years and have produced results, but for some mysterious reason I've been blocked from being promoted to a higher position.
2. Many of the employees in other departments were promoted to higher positions after working as part-timers for a short period of time, but I was kept blocked from being promoted for some inexplicable reason.
3. It is incomprehensible that only some employees were given preferential treatment at the company.
4. The lack of safety and health in my working environment.
5. I consulted with the public office about the suspected labor law violation, but it was incomprehensible that there was no improvement at all.
6. It is inexplicable that the company's awareness of legal compliance has not improved at all, even though there were many acts that were suspected of violating various laws and regulations.
7. It is incomprehensible that the problem of the company was reported to the supervisory administrative agency, but it was not improved at all.
I quit my job because I was fed up with such a terrible working environment.

The first thing I felt after retiring was the loneliness of the dwindling points of contact between myself and society.
I thought that in today's Japanese society, unemployment makes people even more lonely.
Moreover, it wasn't an amicable retirement, so I felt the pain of being angry with the company every day.
Isn't anger making people fall to the dark side?
What should people do to avoid falling to the dark side?
I put my own thoughts on these things into this work.
Please listen!

The atmosphere of the song is 80's disco style J-POP.
