A long time ago, there lived a knight who loved a saintess. However, wanting to not hurt the saintess who wasn't allowed to have private feelings, he made sure to keep a safe distance from her. Eventually the saintess died in his arms and the knight swore, with bitter suffering, 'If I get a chance in another life, I'll make sure that you will no longer live as a saintess.' After a long time 300 years, the saintess was reborn. Can their wishes finally come true in this life?
