Obviously, Percy Stanton's doubts were eased by Isabel Smith's explanation. So, his Isabel just didn't want to tell others that she had such an outstanding boyfriend.
However, Percy still spoke a bit arrogantly, saying, "Isabel, am I only worth five million to you? Anyway, I'm also a jackpot worth billions. Oh, no... I'm a priceless treasure..."
Isabel frowned, has anyone ever been so self-flattering? And so shamelessly at that!
But Percy seemed to enjoy it, continuing, "Isabel, you just must feel that becoming the girlfriend of the world's richest man within one year is too overwhelming, and you're struggling to accept it. So, you don't dare boast about your wealth or tell others I'm your boyfriend for fear of arousing their envy, jealousy, and resentment, right?"
