In a sense, I understand why she is so close off with him (Removing the age gap) Her first husband sacrificed his future for her, and he made her regret it Every. Single. Day. She doesn't want to repeat the same mistake, making a young boy with a bright future abandon his dreams to be with her. Yes, he is rich, but she doesn't know, second, who shall accept it? His family will definitely not agree in him marrying a poor woman with no background, no surprise he is hiding his relationship. There are too much risks involved, I can't see a bright future for them. Either he will forcefully take his father's company, getting rid of his brother in the process to be with her without much protestation, or he will do as her husband and abandon all of that to be with her, something she absolutely do not want.
