"I fell in love with you the first time I saw you!
The last time I saw you, I decided to forget you!"
He and she were separated because of their family status, but no one forgot each other. You can only hide love deep in your heart. In his heart, since he can't be with her, then let himself fall completely! As a result, he became a playboy that women were crazy about; in her heart, since she couldn't be with him, what difference did it make to who she was with? So she became someone else's fiancée.
