He pursues her but she pushes him away because she is realistic and doesn’t see a future for them due to the differences in their social status. Ultimately, they still get married but he is cool towards her. She is at a lost as to what she did wrong and is not sure how to fix it so decides the best thing to do is continue to be nice to him in the meantime until things work out.

It is not until her mum and his parents meet that Bai Yan realizes her mum was the “xiao san” (mistress) in his parents’ relationship and he married her for revenge. Kang Jian has never abused Bai Yan, just acts cold towards her but at this point where she is asking for a divorce, he finds himself falling in love with her. Will their marriage be able to survive all these deceits and hurts? How will all these entanglements end?
