Mafia Boss & His White Rose

Lily Harrington is dying, and the experimental drug that could save her is controlled by one man, Victor Volkov, who runs a mafia organization. Her sister Evelyn goes to buy it. The price is far beyond what she has, so she offers herself instead. Victor accepts, with conditions. He keeps the medication as leverage and makes her sign a contract naming her his exclusively. He brings her into his BDSM practices, which she goes along with while remaining uncomfortable. It becomes unbearable and she tries to run. She does not get away. At a gathering of the organization, an older member humiliates Evelyn and moves to claim her. Victor steps in against him whatever it costs. Evelyn learns what happened to Victor in the past, and after that the two of them are easier with each other. Then Anna arrives. She is Victor's fiancée, and Evelyn leaves. Her friend Kate tells her to fight for him. Evelyn is kidnapped, and only then does she find out that Victor pushed her away to keep her out of reach.
