The Alpha's Rejected Daughter
Charles Newman, a lame scientist had borrowed a huge amount of money to support his laboratory by buying a newly invented machine.
Unfortunately, the invented machine got burnt and it affected the whole building as it was burnt down too. He fell into great debt and the owner of the money happens to be the knights.
Alexander Knight happened to be the Alpha who lend him the money and when he saw that he wouldn't be able to pay back, he asked Charles to bring his daughter to be his bride as a payback. He refused and when Alexander couldn't wait anymore, he set out to him and saw his two daughters.
The first daughter who is Charles's real daughter agreed to marry him while the second daughter, who is the stepdaughter doesn't show any interest.
When Alexander Knight set his eyes on the stepdaughter, he became drawn to her and he found out that he was her mate.
The stepdaughter doesn't agree and was forcefully taken along with him and it was there, they started their betrayed hate-to-love journey.
