Promise: Zero

Ye Xi wakes from her confusion and wanders aimlessly onward through one long stretch of years after another.

Later, when she learns the truth, she finds a purpose for everything she needs to do. But in the end, she realizes her purpose may not have any purpose at all.

As her memories slowly return, the truth she once believed in becomes a ridiculous joke. Her lover and family members become unrecognizable before her eyes. The only thing that keeps her going is the gentle silhouette in her memories.

As she walks through the world, Ye Xi begins to feel like she is an unnecessary person. The things she does are unnecessary, the words she says are unnecessary, and even her entire existence seems unnecessary.

Until the person in her memories gains a face and a form, and truly appears before Ye Xi...
