He was not color blind in the novel. I was thinking the same while reading the novel that why is it not showing that he is color blind. But till the end of the novel, he was a normal person. Even I have a feeling after watching the trailer that there will be a breakup but in the novel, there was no breakup. I think many scenes and plots are added for making the drama.
First ep beginning did really gave a hint of them being childhood sweethearts or am I thinking too much😂
According to the novel, they met each other when he was six and she was four. But he does not remember much of it. He did not even know that she was that girl. After marriage they got to know. But I don't know whether it will be shown in the drama or not.
I liked the ending but at the same moment, I found one thing very disappointing. Lei Chu Xia remembers every memory of them, the time they spent together but Xu Xiao Dong doesn't know anything. They could have shown that they met after 10 years and he remembers something(not the whole thing but some part of it)
It's neither sad nor happy. I mean that when she again went back to 2011 she tried to save his dad and him the patent so that he lived on. Xiao Dong went overseas with his dad and so they never met. Then it takes 10 years to leap. Now in 2021, her best friend, Yuan Yuan was going to get married but Chu Xia did not know to whom. On the wedding day, she got to know that it is Jin Xia Rui and his friend is Xu Xiao Dong. So they again met each other, thus it's like the beginning of their new love story(where remembers everything of the past whereas he did not)
