Higanbana ni Kumo

In the Taisho era, when Japanese and Western styles were mixed, my best friend who attended the same girls' school as me died. It was a really sudden event. Shortly before she died, she told me, "A cluster amaryllis is you." It was a mystery that she left only for me that didn't have to be solved. I look back on the past and try to find the meaning of the remaining words.
