The air in the pitch pits was a thick, viscous heat, a place where the earth's heaviest bitumen pooled in slow, black waves of primeval tar.
Xuan sat on a ledge of hardened asphalt, his fingers tracing the slow, sluggish flow that looked like the blood of a planet that had stopped moving.
"The world is sticking tonight, Ning. I can hear the city above miring itself in its own progress, trying to pave a road that leads back to where we started," he rasped.
The extreme level of his jealousy had turned the very concept of a path into a rival, as if the tar were trying to trap her before he could.
Ning lay submerged to her neck in the black pool, her body a pale moon sinking into a sea of absolute, unreflective night, her eyes closed in a calm ecstasy.
"Let it stick. The progress of the surface is just a slow drowning in traffic. My only true stillness is the way your arms bind me to the floor of the world," she whispered.
She reached out, a black glove of tar clinging to her arm, her extreme level of misery seeking the anchor of his heavy presence in the vault.
Xuan didn't offer a hand; he watched the black liquid coat her skin, his eyes burning with a possessive need to be her only suffocating weight.
"Wei Chen bought a paving company today. I heard it on the industrial band. He's trying to cover the ground until the earth is as flat as his memory of you."
The misunderstanding was a jagged blade he kept sharpened; he couldn't see the rival's labor as anything but a claim on her physical, solid existence.
Ning's face contorted with an extreme anger; she splashed the tar with a sudden, heavy hand, the black liquid falling like lead in the dark vault.
"He's looking at roads! He's looking for a track while I'm right here, living in the pitch and the absolute fire of your heart, Xuan!"
Her extreme level of cryingness returned, a sudden, heavy flood of her soul that the black pool absorbed without a single ripple or sound.
Xuan's jealousy flared into a manic energy; he pulled her up until they were chest-to-chest, his breath hot and smelling of the dry, ancient earth.
"I'll find a way to melt the roads. I'll turn his equipment into a pile of slag so he can see what it feels like to have no direction left to follow."
The extreme level of his possessiveness was a physical hunger, a need to dismantle the rival's vision until nothing was left but the current debt.
"Don't go back up. The surface is a road of lies. I'd rather have you here in the pitch than lose you to a world that wants a journey."
Ning's extreme level of devotion was the only thing keeping her heart beating, a sheer act of will that defied the heavy, toxic pressure of the vault.
Xuan looked down at her, his expression a mask of shattering, extreme misery, and he buried his face in her neck, his body shaking with a sob.
"I won't leave. I'll stay until the pitch turns to stone. I'll stay until the earth forgets that there was ever a sun or a sky above us, Ning."
The misunderstanding of the surface—that they were victims—was the only mercy the world had left to give them in their self-imposed, lethal exile.
Xuan stood up, carrying her through the narrow passage where the walls were slick with the black sweat of a thousand forgotten industrial cycles.
"We're moving toward the old diamond vaults. It's a crystal tomb of silence. No one has checked the pressure since the first heart was broken."
He set her down on a pile of black insulation, his hands immediately searching her body for any signs of the tar-burns or the dry, cold air.
"You're black, Ning. The earth is trying to steal the light I gave you. I should have wrapped you in the silk from the first night in the vault."
His jealousy was so extreme that he was now envious of the very pitch for being able to coat her, as if it were a rival trying to hide her.
He began to rub her skin with a manic, obsessive intensity, his movements predatory and ritualistic, a claim of total, absolute ownership.
Ning leaned into him, her throat exposed to the dark, her misery turning into a jagged, ecstatic peace under the weight of his obsession.
"The silk is gone. The night is a memory. I only want the friction of your hands, even if they turn my heart into a black, frozen ghost," she crooned.
The 100th chapter of their descent was a study in the narrowing of a world, a place where two people became the only two points of gravity.
The misunderstanding of the world above—that they were dead—was the shield they used to build their own private comedy of pain and love.
Xuan pulled a heavy iron bar from the wall, his mind already calculating how to collapse the shaft that led to the city's transport center.
"I'll bury the engines. I'll turn their center into a hole in the ground so they can see the void you really live in, away from their cars."
Ning watched him, her heart aching with an extreme level of devotion that saw his paranoia as the ultimate form of a love letter to her soul.
"Bury it all. I don't want their movement. The movement is where people lie. I only want to be the truth in your eyes, in the shadows of the pitch."
The extreme level of her possessiveness over their secret was her only pride, the only thing she had left of the girl who once owned a name.
Xuan returned to her side, his face covered in the dust of the deep, looking like a ghost that had finally found its black, toxic throne.
"You are mine. In the pitch, in the black, in the silence. Mine."
The misunderstanding was a distant memory, a flicker of light at the end of a very long, very dark hallway they had long since abandoned.
They were the only two inhabitants of their own private universe, a place where extreme love was the only law and jealousy was the only god.
Xuan lay down beside her, his body a barricade against the cold, his arms a cage that promised a safety the light could never provide.
Ning closed her eyes, the rhythm of his heart a lullaby that drowned out the whispers of the past and the hum of the city above.
They were safe. They were alone. They were together.
And in the darkness of the diamond vault, the debt was finally, irrevocably, and beautifully cancelled by the weight of their shared obsession.
Xuan's hand remained on her throat, a gentle, possessive pressure that reminded her she was alive only because he permitted her to breathe.
And in that pressure, Ning found the only security she had ever known, a love so extreme it was indistinguishable from a beautiful death.
They were Xuan and Ning, and they were the masters of their own destruction, a couple bound by a love that was too extreme for the living.
The chapter closed on a darkness so heavy it felt like the weight of the entire world was pressing down on their locked, cold, and smiling lips.
They were happy in their own, twisted way, two broken mirrors reflecting each other's shadows until there was nothing left but the black dark.
The debt was a ghost, the rival was a memory, and the love was a cage that they had built with their own hands out of blood and pitch.
And in the absolute blackness of the shaft, the only light was the spark of an obsession that refused to be extinguished by the weight of the world.
The end of the day was the beginning of their forever, a cycle of obsession that would repeat until the earth itself forgot the sound of their names.
The 100th chapter of their descent ended in a silence so profound it felt like the weight of the entire world was pressing down on their lips.
But they didn't mind the weight; they were together, and in the kingdom of the buried, that was the only truth that held any weight at all.
