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).

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.
