The story has multiple main characters even though it would be mostly narrated through the POV of Ralf "the transmigrator".

All the Princes would fight for the throne and if possible even sacrifice their women or seduce other's women to accomplish their tasks.

Thus, themes like NTR would be used frequently. If you hate NTR I would still urge to try once, somehow it is different and you will understand when you read on.

If you are still uncomfortable with this theme, then leave immediately ^_^.

Any gift starting from, inspiration capsule to higher ones = 1 more chapter respectively (+_+)(+_+)
