Wei wei, you're cute and I do feel bad for you, but honestly, you're just getting a taste of your own medicine.…
I think he's punishing himself. He thinks that CC still loves WS and that he doesn't deserve his love. So he said that (hate when they do that in dramas).
is it dubbed by different people ? It seems like the audio is not the one from the video ?if so, why ??
All Chinese dramas are dubbed. Because there is a lot of noises on set and lots of different accents in China so the actors may have not a standard accent and sometimes because the voice doesn't match. And also I think it's less expensive to do this way instead of having good sound engineers. Most famous actors and actresses voice over their own characters but not all of them. In this drama, only Zi Yu (WeiSu) voice over his character.
And also regarding the comments about the lack of chemistry. They're not supposed to be in the passionate, attraction phase. They grew up together they have a deep bond based on their experience together. And they probably got married because they grew up together and were emotionally attached. They're not going to look at eachother blushing and have big declaration. Plus, they had this fall out and it's not easy to come back from that. Despite everything, I can see in their eyes that they really care for eachother. I feel like everybody can have their point of view but don't compare what is not similar.
