Just read an interview with the writer of the drama, and would like to share a couple things she said, which I find interesting.
It took the writer four years to adapt the novel to the screen, and lots of changes have been made. In the original novel (same name, published in 2012), XKL is a soldier and MK is a military doctor. They kept the profession, but decided to make XKL a SWAT police and MK a normal doctor instead, to make it easier to design the plots.
The XKL character in the novel is more experienced and shrewd in relationships. However, when doing field studies with actual SWAT police, she realized that they are very simple people and usually do not have much dating experiences. Hence, the writer decided to change XKL into the type of character we see now. I must say this definitely made the person much more cute and relatable. :-))))
As for MK, they think it is important for her to have her own career. She can be naive in love, but not simple minded. She needs to have a strong personality.
They also decided that they would not do love triangles just to make it dramatic. They are like: the audience knew from the beginning that the two leads will end up together, why toying with their emotions (AMEN!!!). They want the audience to be relaxed and happy when they watch the drama. :-)
The writer also talked about how the plot will move forward from now, and the focus will be on personal growth. She said that it will be about smaller things in life, which will be relatable to the audience, and it will make them grow individually and collectively in the relationship.
Finally, the writer commented on the two leads and contributed lots of the success to them. She said that Bai Jingting has surprised them greatly - he would design lots of details and dimensions when he acted, while Sandra Ma suits the character well as MK needs to be stubborn while sharp at the same time.
