When Starscream and Black Spider stayed together, when Starscream's mind was taken away by his father, when Starscream tripped over a stone, when Starscream met the innocent girl, at that time she didn't know the meaning of a glance for ten thousand years, at that time she didn't understand that the thread of fate would be entangled with only knots that could not be untied. No matter how beautiful the miss or encounter is, it is always cloaked by chance and exerts an inevitable influence. Existence is reasonable, and occurrence is a foregone conclusion. Why ask why, why feel sad about the loss, anyway, it is just a coming and going, an encounter again and again, but again and again.
