This is the challenge that I am writing this fic for. I don't remember where I found it or anything like that. Please read and review.
Angelus Keane finds out on his 30th birthday, he has been stripped of his various trust funds because the original principle has reverted as scheduled back to his mother and he over the years has squandered most the earnings. He is left with approximately $50,000 and no work experience or desire. He returns home to confront his mother. She refuses to restore the assets. His parents had assumed he would have allowed the earnings to grow and made investments to secure his own future. And also be able to support himself by now.
But she will consider setting up new trust funds for his wife and children if he marries someone she approves of. A woman from a proper family in society. She even suggest the daughter of close friends Frederick and Amelia Chase. She also offers he can stay at the family home if he helps with his younger sister Druscilla. Druscilla has the mentality of a 6 year old due to a fall from her horse as a child. An accident no one knows was caused by her angry older brother. A sister he hates to be around.
Upon returning to his penthouse he has to decide what to do. He decides to find a woman his mother will approve of but one who he can easily control. He also wants her to be desirable if he is going to be stuck with her in his home. He sets out to find the youngest, prettiest female in the "acceptable" society. He finds 16 year old Buffy Summers.
You can figure how he finds her. He has to get her as his bride in an abnormal way. And of course he has to learn she is not as controllable as he expected.
