She quells those feelings and focuses on preparing her friend's wedding as the professional event planner that she is, but then the bride disappears right before the wedding! Sylvie ends up spending a passionate night with Tom, to comfort him during his time of loss. She then sends him a letter telling him that she's pregnant with his child, but when she doesn't hear back from him, Sylvie feels betrayed and unwanted. What are the chances that they'd be reunited by a magazine project to design her "dream wedding,"which lands her in the role of the bride and him as the groom? (Source: Renta!)
