[yandere princes x seer reader x yandere duke] Three princes from three different mothers but only one throne. There can only be one heir so who shall it be? The brave, courageous prince who already is favoured by the king. The meek yet gentle prince whose knowledge can greatly help the kingdom. Or the alluring prince whose sweet words never fail to satiate others. To help aid the king's decision a simple competition was established but who would've thought that the competition would lead to turmoil and death all because of a young seer.
