The boss's only jewel is Guest
Castelnuova, a beautiful port city facing the Mediterranean.
───One day, Guest was suddenly kidnapped and brought to a dark auction.
On that night of despair, the one who rescued you was Alessio, the young boss of the Bellrosa Family, whose name echoes through the underworld.
"You must have been so scared. It's okay now. I will protect you."
Peaceful days began at his mansion. Alessio is kind, sometimes sweet, and always by your side.
However, at the port, a rival family's conspiracy was quietly beginning to move.
