Dahlia felt there was something terribly wrong with this arrangement by Henry.
She sensed that Henry didn't tell her the whole truth because there was no way in hell a woman like Kate would be willing to marry Henry while being treated like a mistress.
Why? Because Dahlia already concluded that Kate was a woman with principles in life.
