Answering some of the questions posted above: Sou Jun's character was changed for the drama. He actually appears in the novel quite a bit and he doesn't get hurt either. Same with Jiang Ju, his character was changed for the drama, or rather expanded. It was mentioned he did go on a blind date with Xu Qin, but to my knowledge, Song Yan is unaware of this the whole time, even when Xu Qin finally introduced them at the bar. Xu Qin does not goes down to the wreck in the novel, it seems they added more drama to this. I am also wondering about Song Yan getting the fibrillator treatment, that is not in the book.
