[Synopsis]
[How could a slave know more about money than a master such as I] A quote by the president of Hanbo Group, Jung Tae Soo during the Congressional hearing. They are called employees, salarymen, but in truth they were slaves. I was a slave. But I’ve put everything I’ve had to become a butler. Instead, all I’ve got was an ending befitting of an abandoned slave. And the blessings of the god.
[Reason]
First there are some korean novels here on QI so this should not be impossible.
This is ranked number 1 in Munpia.
There are not many Modern Day time-travel rebirth/transmigration novels, specially that are realistic and deals with politics, business and has a mature protagonist.
There are many that play games after time traveling but not many that deals with politics and business. The only I know is [Extraordinary Genius] but there is nothing wrong with having one mire besides these two not same.
