Traumas: The only one he had dared to call family had abandoned him, without even a simple goodbye.

Backstory & Lineage
Birth Secret: His "great-grandfather" is actually a Specialist of unfathomable rank who created a false ancestral trail to hide Yè Yī's origins as well as the original creator of the Soul Arm, which is sort for by many but he never got to complete it.
Soul Arm Creation: As a child prodigy, Yè Yī created the Soul Arm—an unorthodox Arm born of will, not element or substance. It proved too powerful, so he dismantled and hid its pieces.
Void Affinity: No one knows how he awakened the Void aspect, which traditionally isn't inherited. It may be linked to an ancient entity or contract sealed within him.
---
Interpersonal Dynamics
Violet: Deep mutual respect. Only he will even try to share emotional intimacy with. If he was the hollow, she was the sound.
Qiū Huà Bǐ: Treats him like a stray puppy, in need of a way to go. Yè Yī sees in him the freedom he lost. Pretends to be nonchalant but will protect him fiercely.
---
Symbolism
Color Association: Icy silver and black void — frozen truths, lost time, and the nothingness between worlds.
Relic: A soul-core pendant embedded with a frozen tear. It hums faintly in his presence.
The Yè's family plaque, who's significance is yet to be unravelled.
Forged Title: The Architect of Hollow Things
---
Unspoken Burdens
He Remembers Everything: He fakes forgetfulness to cope. Every failed timeline, every death, every sealed Arm fragment—it's still there.
Something Sealed in Himself: A piece of the Soul Arm still resides in his body. Removing it would either consume him—or unchain him.
Emotional Apathy: Has nearly been able to portray a genuine emotion since he was four. He Can't Love Freely. He avoids closeness not out of disinterest, but because he's forgotten how.
Avoidance: Would rather stir clear from confrontation unless backed into a corner.
---
Weaknesses
Iceback Syndrome: A degenerative effect of prolonged Ice Arm usage. His physical temperature often dips dangerously low.
