I think Mills and Boons titles are probably generated by a very simple grammar: The [Nationality] [High-powered Profession]'s [Asdjective for Sexy] [Synonym for Lover]. Eg The Turkish Millionaire's Sultry Mistress, The North Korean Cadre's Sleazy Hooker, etc.
But I think your project could be AI-hard - to write a compelling story you'd need to have a virtual world with virtual characters with virtual psychologies. You'd need to be able to model complicated stuff like "Romeo knows Juliet thinks he is already dead", and simple stuff like "If Romeo is under Juliet's balcony, he can't see her until he climbs up". Interesting project though.
