The night before she leaves for her hometown of Dublin, in hopes to start a new life, a man approaches her at the bar where she works. He's gorgeous with dark hair and olive skin. She's never had a boyfriend before, but she decides to have a passionate one-night stand on her last night in London. The next morning, Vicenzo tells her in a cold voice, "I'm Allegra's brother. I slept with you for revenge."
