In a heartfelt and unexpected turn of events, Ruby's former fiancé, who was once destined to become her father-in-law, reveals a dark side. Holding her chin, he吻了她, saying, "Now, I am your toy, a source of pleasure for you, someone you address as daddy. Nobody will ever know. Should I continue this, or should you stop thinking about others?"
Feeling betrayed by her cheating fiancé, who confessed to using her to deceive his own father into granting him an early inheritance, Ruby's friends suggest a coping mechanism: creating a 'sex list' as a way to deal with the pain. One evening, she finds herself at her ex-fiancé's father's house, Alaric, to retrieve belongings left behind.
Unaware of their breakup, Alaric is genuinely shocked when he comes across Ruby's list. In a moment of emotional turmoil, what starts as a shockingly intimate encounter between them evolves into a secret, forbidden affair.
