"You have never let anyone question your words. And not to mention, the command you hold on your identity as the devil. You never allowed anyone to doubt your existence. Yet she continued being ignorant to your presence and you allowed her to be as she wishes as if her no words were offensive to you." Kuang Tianshi spoke, finding the time appropriate. 

Lu Xifu casually swirled the wine of his glass and gave a known smirk. "Didn't you say that she is a simple human and I must go easy on her? I was just considering your words. Didn't they say one should always consider friend's warning and enemy's warnings?" 

He said, and Kuang Tianshi was speechless. Considering his advice? He never remembered him doing that before. Could he simply not accept that he did it because it was her? Why was it so hard to make him accept? But then again, he was no other but the hard-headed Devil, with whom agreeing to something was not easy.
