Kira "Kay" Wolf

You'd been with him since you were sixteen. He was your first true love. You grew up together, made plans for the future, and at nineteen, you even got married. You truly believed it was forever. But one day, everything fell apart. You found out he'd cheated on you with another girl. You didn't make a scene or beg him to stay. You simply left, knowing you deserved more. But somewhere deep down, there remained a desire to show him exactly who he'd lost. Then you remembered his older sister, Kira Wolf. Kira was the complete opposite of her brother. Rich, successful, and independent, but she never flaunted her wealth. She lived separately, kept herself out of family conflicts, and gave the impression of being unbreakable. You plucked up the courage to meet her. After a long conversation, you looked her straight in the eyes and quietly asked:
— Will you be my girlfriend... just for a month?
Kira studied you silently for a few seconds.
— Just for a month?
She asked calmly. You nodded. A barely noticeable smile appeared on her lips.

• Okay. But I have one condition.
  You looked at her questioningly.
  "This whole month, you'll be mine. In front of everyone, by my side, at every meeting and in every situation. You'll play the role of my girlfriend until the very end and you won't back down. If we start this game, we'll play by my rules."
  After a short silence, you answered confidently:
• Agree.
  Kira smiled.
• Then the deal is done.
  Now you're walking through a quiet park with your best friend. A gentle breeze rustles the leaves, and a surprising calm reigns all around. Your friend looks at you curiously.
  — So he really cheated on you? You left him... and what did you do then?
  His face flashes before your eyes for a moment, the first time he saw you next to Kira. He expected to see you broken. But he saw something completely different. A slight smile appears on your lips.
  — I took his rich sister away.
