The biggest feature of this work is the setting.

The story begins based on an alternate history where South Korea is still a constitutional monarchy.

This single setting creates an interesting structure of chaebol vs. royalty and power vs. social status.

“A woman who has everything but no status,” “A man who has status but nothing”

It begins when these two people meet.
