​Shori Himesaki has always had recurring dreams of a medieval world where a valiant knight protects a beautiful princess. He's spent his life idly assuming that he must have been the knight in a past life. ​But that all changed at his high school entrance ceremony. The moment he lays eyes on Asako Kishi, the truth hits him: his past life wasn't the knight's at all. ​He was the princess... and she was the one sworn to protect him.
