The twin daughters of the Romano family—Europe’s most powerful crime syndicate—lead completely different lives. To protect her twin sister Isabella, older sister Victoria stepped into the underworld at a young age, leaving the chance to live in the light as an ordinary person to her sister. Isabella concealed her identity and entered an elite private school under the guise of a “poor straight-A student,” only to become the target of a group of wealthy second-generation heirs led by Liam, the heir to a financial empire, and Chloe, a vicious school bully. During an especially brutal bullying incident, Chloe pinned the blame for stealing a rare, 10-million-class limited-edition watch squarely on Isabella. Liam, looking down on her from on high, not only condoned his henchmen’s inhumane beating of Isabella but also locked her inside an abandoned cold storage facility at minus ten degrees Celsius. Isabella froze to death in despair and extreme cold, her hand still clutching the birthday gift she had intended to give her sister. Victoria, who had just annihilated a rival family in a violent clash between underground factions, returned home only to find her sister’s bruised and lifeless body. Her overwhelming grief transformed into the purest murderous intent. Victoria donned a school uniform identical to her sister’s and put on a pair of gold-rimmed glasses to mask her killing intent, then strode through the gates of the aristocratic academy like the Grim Reaper.
