Hakuou Academy, where sakura petals drift everywhere. Chizuru entered the school as its only female student. Surrounded by her teachers and sempai, she led a very silly but fun daily school life. However, there was just one thing that never stopped bothering her. Sometimes it seemed that there was something terribly sad about the gazes of the young men when they looked at her. Chizuru could think of no reason they would feel that way, and even when she tried asking, her questions were waved off with smiles. The cherry blossoms that they watched together long ago had started to change Chizuru's feelings, and those of the young men, once again--- They who were reborn still holding onto the regrets of their past lives, and Chizuru who alone remembered nothing. This is their sorrowful, tender love story.
