The Butterfly and Her Puppy

She saves him before her stepsister can get to him. She has been reborn with a single aim, which is money, and the second chance lets her reach him first. He is the heir to a rich family and is passing himself off as a broken young man with nothing, the sort people call a puppy. On the day he is forced to drop the act and show who he is, she takes a large sum of money and disappears without a trace. It wrecks him. The soft young man she knew turns possessive and obsessive and comes apart. Other men are competing for her by then, and the heir starts a long campaign to get her back, willing to pay whatever it costs.
