What are the plots in My Bargaining Queen that make you cry?

My Bargaining Queen is a TV series based on a novel of the same name. According to the information I found, the play tells the story of Sheng Zhenning, the president of Changsheng Group, who met the haggler Xia Shao because of a misunderstanding. They love and kill each other, grow together, solve many mysteries and difficulties in each other's lives, and become sweet lovers.

There are many touching plots in this TV series. For example, Xia Qian met Sheng Zhenning, the owner of Changsheng Hotel, at an engagement party. In a bad mood, Xia Qian blamed all the problems on Changsheng Hotel and Sheng Zhenning, because his fiance He Zhijun was temporarily married. In the disagreement with Changsheng Hotel, Xia Qian found that his super insight and analytical power had great potential in bargaining, so he began to learn bargaining skills and became an excellent bargainer. In this process, many touching stories happened between Xia Qian and Sheng Zhenning.
