There's nothing more torturing than the scene of your future wife being owned by another man. It wasn't only Edmun's Huang's heart that was torn to pieces right then, at the sight of Dian being intimate with another man, but also his ego.
He knew he had been very wrong on how he treated her previously and he had already paid for it. Yet Dian thought his punishment wasn't enough and so she went as far as stripping off his ego by making him watch her seducing another.
He hated such a sight and he immediately turned his back onto such a scandalous scene but Dian's loud moans haunted him all throughout the night. She promised him an heir and if this was the way she was to give him an heir, he'd rather not have it. But what can he do then? He was not in the place to even lash out and be angry with her. All he could do was just watch her do all her misdeeds shamefully.
Who knew the second miss was this wicked?
