Prologue
"GuangGuang, Captured by the Desert Cannibals."
Creak— Creak— Creak—
The sound of rusty iron chains grinding echoed through the darkness.
So I’ve finally been caught.
With wrists and ankles bound in cold shackles, GuangGuang looked up at the ceiling. A faint light seeped through the damp stone walls. Somewhere nearby, there was the smell of roasting meat. He couldn’t tell whether it was human flesh or animal meat. No—he didn’t want to tell.
Even if I had to die, I didn’t want to be eaten by cannibals…
At that moment, heavy footsteps approached.
"…!"
A cannibal stopped in front of GuangGuang. A massive warrior with red tattoos covering his entire body. With rough fingers, he poked at GuangGuang’s arm, as if checking the freshness of meat at a market.
"I’ve never seen brown skin like this before."
…What?
The cannibal was speaking.
"You… can talk?"
Then the cannibal suddenly grew excited and began pouring out words.
"I can talk. A little. First time seeing your skin. White skin is mild, black skin is chewy. Your brown skin, I’m curious."
His fingers moved from arm to shoulder, from shoulder to side. It wasn’t ticklish—it sent chills down his spine.
"My name is… GuangGuang."
He didn’t know why he had said his name. Because he wanted to live? Because he wanted to buy time?
The cannibal grinned.
"GuangGuang? GuangGuang, sounds salty, seems delicious."
……How did things end up like this?
The story goes back ten days earlier.
