“I wanted to play with you… punish you. But now, I want to ruin your world and turn it pitch black. Isolate you, so you have nothing left except me.
And remember, it’s your own fault.”

ISOLATION. LONELINESS. ENDLESS SILENCE STRETCHING INTO ETERNITY.
This is the personal living hell of police detective, Kuon Leiris. His punishment for ruining the Black Duke’s deal. But when night falls, it gets worse…
Cruelty. Affection. Madness. Obsession. Constant mind games where he can do nothing but give in. Yugo pours his every corrupt desire into his prey, testing the limits of their capture-bonding relationship.
Do you dare enter a dark world where safe-words don’t exist?
