Legend has it that whoever is put on an OK collar engraved with the emblem of the "Thirteen Families" will become its Servant unconditionally.
She didn't believe it! Boldly trigger the law and rush into the devil's territory!
It's over! When the collar that imprisoned freedom was placed around her neck, she could only hold her ears and kneel on the keyboard, bowing her head and saying: OK, my master.
But the little devil inside is showing its teeth and claws! What kind of resistance will she make if she is born with a sanguine temperament? And in order to conquer her, what kind of trump card will the young masters of the "Thirteen Families" use? !
All the surprises and romances you can imagine or cannot imagine - all bloom between "OK" and "Your Excellency".
On this cool autumn day, you are my Master!
