After all the sadness and pain, Adrian thought that he somehow came across Cassidy who was kind enough to have mercy on his desperate, loveless heart.
Even though he knew he was not worthy and even though she could have done better - even though she could have had anyone else, she still chose him in the end. That's not because he did her any sort of favors. It's not because he has a high status, is famous, and owns more than billions in his bank account, but it's just simply because she respects who he is and accepts him in all his weak and powerless state.
'That was all I ever dreamed of. It was all I could ever hope for,' Adrian thought with a contented smile on his face, holding Cassidy tighter in his arms.
She is still here. With him. He would not be able to bear it if she were to disappear out of nowhere.
