Whether two people are sweet or not depends on the film and television drama. Whether two people will be together is not the fact that many naive cp parties think that they are sweet words to each other. Eye contact can tell. This is a practical problem. Once two people are together, values and outlook on life are all factors that may lead to disagreement between them. Besides, William Chan's career was almost ruined by his two ex-girlfriends, and now he is also secretive about mentioning his feelings in public. Even if he wants to fall in love, he should find a woman who won't bring a devastating blow to himself this time.
A person who is willing to be a little woman behind her back can wait for a career of ten years with peace of mind. But obviously, Zhao is a stronger person and will not give up his career for a man. Both of them are strong, and the growth environment is also very different. In fact, there are not many common languages (cp fans don't say that they often whisper to each other, and how much common language has little to do with how much they speak).
They can be together, unless one of them makes a career sacrifice, but I personally don't think these two hard-working people will do so, so the conclusion is that it is too slim to be together. Even if we are together for a period of time, the possibility of lasting is very small.
