Chen Feng being so proactive in confessing made both women feel somewhat uncomfortable.
They would rather Chen Feng not say it, but since he already did, they have to bear with it.
Sun Xiaorui isn't in a position to say anything to him, Wu Mengting has an agreement with him too and knows he is now suffering from a terminal illness that hasn't healed.
For Sun Xiaorui, it's relatively easier because she's already come to terms with it; she herself is being supported by Chen Feng, and Chen Feng initially also made a verbal agreement with her. So, despite feeling uncomfortable inside, she quickly adapted after Chen Feng's confession.
For Wu Mengting, however, she really feels uncomfortable; she particularly cannot accept how Chen Feng and Jin Xinyan just met, and then went to a hotel that night.
She really dislikes Chen Feng's promiscuity, even starting to feel somewhat repulsed.
