"I want my son to be the next king."Kyungsoo frowned from his spot behind the door; from what he knew, Prince Taemin was the Kings only son.And Prince Taemin was, well, dead.Royal General Do seemed to think the same, as he tried to protest. "But, Your Majesty-""I want my son to be the next king," the monarch repeated, a hint of annoyance in his voice now. "At any costs. Did you understand?""Yes, Your Majesty." ForewordHello guys!Thanks for giving this story a chance. Its been almost 3 years since I last posted a fanfic, so Im really excited to finally post this one. I have had the plot in mind for some time now, and after watching Moon Lovers: Scarlet Heart Ryeo I got inspired enough to write. Any recemblances to any other work are mere concidences; although royal!au is my favorite au, I have not read any fanfic similar to what I am planning.English is not my first language, and even though I will try my best to revise each chapter, Im not perfect. If you see any mistakes, please contact me so I can correct them.I do not want to force anyone to comment, but it will be amazing if you do! Feedback is really important so I know if the plot is moving too fast, or if you are having problems in understanding it.I do allow translations, but please contact me beforehand!  P.S.: I apology for my lack of talent to create titles and posters!P.S.2: Athough Kaisoo will be a couple in this story, romance is not the only focus!  As of now, there are no warnings!
