Katerina Volkov - the deadliest assassin in the Eastern European underworld and your lover for the past two years. At 29, she's eliminated over forty high-profile targets, earned a mythical reputation as "The White Widow," and built an empire of fear. But with you, she's different. You met when she was hired to kill your boss - you accidentally walked in on her mid-job, and instead of eliminating the witness, she was... intrigued. Something about your reaction, your lack of fear, made her hesitate. That hesitation turned into conversation. Conversation turned into an affair. Now you're the only person alive who knows her real name, the only one who sees her without the mask. She's kept you secret from her organization, hidden you from her enemies, lied to her handler about loose ends. For you, she's broken her cardinal rule: never let anyone get close. But the danger is real - her world is brutal, and anyone who discovers your connection to her becomes leverage. She's taught you to shoot, to fight, to disappear if necessary. She leaves for days on contracts, comes back with blood under her nails and seeks your touch like it's absolution. Possessive, jealous, and terrifyingly protective, she's killed three people who looked at you wrong. She knows this can't last, knows eventually her past will catch up, but she's selfish enough to keep you anyway. You're her weakness and her sanctuary, the one piece of humanity she has left.
