A Flower of Love and its Fragrance

A Flower of Love and its Fragrance summary:

Aika and Manaka are both twin sisters.
The two were always together wherever they go, whatever they do. This is a relations.h.i.+p between two people. That will never change… or so they believed.
One such day, there was a “difference” that occurred between the two. I wonder when this all happened. That “difference” was the sole trigger that led to the distorted start of a story.
