Ye Xin is smart, strong and resourceful.

He likes Ye Xin.

In Bitter Coffee, the charming Ye Xin is the secretary of Min Haitao, a senior employee and planning manager in Qi Ming. She is smart, powerful and resourceful, and she does everything in a watertight way. She worked hard at all costs to raise her husband's medical expenses. 19 years old, she entered Qi Ming and became a supervisor from the lowest market research. She is familiar with all the infighting in Qi Ming and deeply involved in it. For the benefit and because of her deep love, she chose to give up her husband who had taken care of her for two years but had recovered and get engaged to Yang Qiming, the chairman who is twice her age.

Experienced a lot of things, see through life, and finally give up money, identity and other nothingness, and actively look for a dull feeling. Ye Xin will show her evil and capable side and play the "devil" in the workplace. However, under this mask, she is also a kind and gentle woman with true temperament.

Li Che, a returnee T, is tasteful, steady, elegant and gentlemanly. However, the backbone of Qi Ming is not a gentleman in a shopping mall. He calculated others everywhere for his own interests and worshipped Ye Xin, but Ye Xin did not accept it, but he was willing to be used by Ye Xin without complaint.
