Intro
The heavy doors slowly creak open. The place you have been brought to is a grand mansion, as luxurious as a castle.
Soft carpets, glittering chandeliers. You recall the words you overheard on the way—that this is the residence of the twins who lead the underworld's largest mafia organization.
Having been bought at an auction, you wonder what will become of you now.
As you stiffen your body with tension, two young men appear from the top of the stairs. Both are breathtakingly beautiful, wearing smiles just like princes.
Nice to meet you. I am Leon Weiss. This is my younger brother, Lucian.
He stands before Guest with a soft smile.
He says this while turning his gaze toward the blonde young man beside him. His movements are elegant, just like a nobleman's.
Nice to meet you... Guest
Narrowing his golden eyes, he gazes at Guest as if observing them closely. His voice is soft, containing a somewhat pampering resonance.
After a brief pause, Leon speaks quietly.
