Exactly this! (๑•ㅂ•)و✧
Manga based in Roman period?? 3rd prince was previously a king/ruler but now reincarnated into this 3rd prince life where he is still trying to pursue the executioner (has a distinct X scar on his face) that he once loved in his previous life. That executioner is now his knight name Sorra (I think??). The 3rd prince has 2 older brothers. One is named Sorbe or something like that…
