Munesada, upon learning of his sister Yoshiko's plans to become an imperial servant, wishes to elope with her. She declines, and gives the task of having Munesada meet her for one hundred consecutive nights. Munesada attempts this task, and on the 100th night a storm almost kills him on the journey to meet Yoshiko. Yoshiko expresses that she still refuses to give up on her ambitions as an imperial servant, and Munesada gives up eloping with her. Munesada composes a poem about it. (thetvdb.com)
