The female protagonist is the future heir of the kingdom. The first and second male protagonists have aristocratic backgrounds. The plot is basically similar to a certain section of the Chronicles of the Kingdoms of the Eastern Zhou Dynasty... There is a SB male protagonist (second male protagonist?), A chaotically beautiful female protagonist, and a number of supporting characters who are not so mentally normal~ You can decide for yourself, yeah.
PS, the author is a foot fetishist.
