I read all the stories and I found them extremely interesting, especially because the plots between the various characters were rendered in very different ways.
However, when I read the story of @calluna I had to surrender to the fact that, simply, the girl can write damn well! I think that her ending is the perfection, speaking of narrative rhythm and of the emotion climax that culminates with the dramatic and spectacular ending. In addition, she knew very well how to sow small hints here and there, that reveal an interesting story of unrequited love and another lost love. So my vote absolutely goes to her.
