From abandoned lover to sudden fiancée—Lena doesn’t know what to think!

A year ago, Lena made love to Spanish millionaire Alejandro, who promptly left her. She decided to take care of their son, Miguel, all by herself. But then Alejandro suddenly shows up and tries to take her baby away. She resists, but he says she had no choice but to marry him if she wants to keep the child. He takes her to a large castle atop a hill in Spain, but Lena still isn’t sure what’s prompted his sudden proposal.
