The hardest part is to choose the title. I had several choices in my mind...
Anyway, this is about the bond of friendship between Zack and Cloud. Both of them cherish their relationship (although Cloud once forgot). However, both of them also endure pain and suffering which I may as well symbolize it as "darkness". They had many problems, but one of the problems that makes them connected is parting with Aerith. Zack died without having a chance to fulfill his promise to Aerith and Cloud is parted because of Aerith's death.
Long story... Anyway, please comment and fav/hug if you'd like! Thanks...
