Don't Be a Kept Man

In this world, there is always one type of man who does not want to improve themselves. They care only for themselves, in whatever means possible. They make their life goal to be kept as a lover, and they will use their lovers up until they have no more use.

Self Reliant System: Our goal is to rise up! Our goal is to persevere! We must be self sufficient and self reliant!

When numerous souls have been bound by the system to enter into the bodies of those who only rely on their lovers, what could this lead to?

In other words, this is a main character transmigrating into a scummy human being, and creating his own destiny kind of story.
