The 21st Shadow

"The perfect replacement hides the dangerous truth."
Seven or Nothing. That was the fandom's rule.
But behind closed doors, Big Hit Entertainment is facing a catastrophic, hidden ruin.
​On the eve of their definitive comeback, a horrific sasaeng stalker incident has left BTS's main vocalist, Jeon Jungkook, comatose in a private hospital wing. To announce a hiatus now would destroy the global momentum the seven boys have bled for years to build.
​Desperate for a ghost to hold the line, the agency tracks down ANONYMOUS-a viral YouTube creator known only by a black mask, a baseball cap, and a terrifyingly flawless vocal range. Assuming from the deep chest register and oversized clothes that the artist is a young man, Bang PD issues a replacement - Min Ji-woo: the eighth member. The wildcard. The replacement.
​But when the contract is signed and the medical clearance drops, the corporate inner circle discovers a ruinous truth.
​ANONYMOUS is an eighteen-year-old runaway girl.
​With teasers already live and the tracklist locked, the agency has no choice. There is too much money on the line to back down. The disguise must hold. She is forced into a high-stress dorm with six grieving, fiercely protective, and highly suspicious young men who resent the outsider taking their youngest brother's place.
​She thinks she's wearing the mask to survive her family.
The group thinks they're keeping a seat warm for a fallen soldier.
​"I didn't choose your group," I whispered, my voice dropping into that heavy, artificial baritone. "I chose the lock on the door."
