Although, this is a very normal physical reaction, and although, at that moment, she thought the man she was embracing was Ziyang, she had always been fearful and resistant to Gu Ningyi doing such things to her. She never expected she would sink into Gu Ningyi's gentle kisses and caresses.
Dong Xin Yan widened her eyes in disbelief, shaking her head subconsciously, unable to accept this fact at all.
She approached feelings with simplicity and conservatism, so she could only accept kisses and lovemaking with love. If not driven by desperation and being left with no options, she would never sell herself and make such a deal with Gu Ningyi.
