In the country's most violent prison, nothing survives untouched. Not the guards. Not the rules. Not the doctor who was never supposed to be there. Dr. Dunk Natachai walks into Ratchanarok believing he's there to fix broken minds. He doesn't realize he's just stepped into the hands of the man who breaks them. Joong Archen - inmate 09, murderer, king of the underworld behind bars - runs the prison like a kingdom built from blood and silence. Every deal, every body, every scream in the dark belongs to him. And now, so does Dunk's attention. Between the sound of knives scraping metal and whispered confessions in the therapy room, something starts to twist - hunger, fear, desire. He's the doctor. Joong is the danger. But inside Ratchanarok, it's hard to tell which one's truly locked up.

It was just a dare. Just one kiss. Just one night. Joong still calls himself straight. Dunk still pretends it meant nothing. But nothing doesn't come with jealousy, late-night touches and the kind of tension that ruins friendships. Friends with benefits was supposed to be easy. Catching feelings wasn't part of the deal.

A new apartment. A cheap rent. A fresh start. That's all Dunk Natachai wanted after his breakup. But the neighbors aren't just strange - they're unsettling. Smiling too wide. Watching too closely. Calling him things he never told them. And next door lives Joong Archen. A man who never leaves traces. A name whispered in FBI files. A ghost who shouldn't exist. Dunk's best friend swears it's safe. Dunk wants to believe him. But when the walls feel too thin, the hallways too quiet, and the neighbors too interested... He realizes he didn't move into a home. He stepped into a cage. Book cover by: lochi ✨
