There's a fascinating proposition, whether humans really can escape the dominion of fate, or in other words, whether the concept of fate even exists.
As a person who merely bides time until death, I normally wouldn't engage in such profound philosophical discussions, but when the issue is thrust before me, I can't help but pay attention.
Lilina felt fate was an issue not worth concerning oneself with, because the concept was too overbearing, preemptively dismissing every possible explanation with those two words. A person can challenge fate, step out of the box, transcend reincarnation, but a few words could render all these glittering achievements null: it was their destiny to challenge fate, destined to step out of the box, destined to transcend reincarnation… it was their destiny to rebel against "destiny." As Lilina said these words, she bit her tongue, mockingly suggesting it was also destined that she would bite her tongue.
Thus, with fate, more words are pointless.
