You mean Ex0? I think they are a group who had a lot of ups and downs and there were clear tension between some of the members. But throughout the time, I believe they got closer (even if they had to, because of their common experiences), they are not necessarily like brothers, but at least they manage to get along somehow. So maybe, they have a chance to remain a whole group. But I think D.o is clearly over it, he wants to be taken more seriously as an actor, so imo, he is someone who might end his contract for good.
Honestly, Lay is a mystery to me and he is the only one who have me confused that much. I always liked him in the past, and thought that he was so kind, always ready to help anyone including fans, thoughtful and with great manners. I felt so disappointed by the way he reacted to this matter, because obviously this whole situation in China is terrible and heartbreaking. I don't know if I am biased but I think that him being a chinese citizen makes him see things subjectively. Also, he is an official ambassador, so maybe he was never given a choice in the first place. But yes, no matter what the truth is, it was an awful move and I didn't expect that from him, I was hugely let down. He might want to have good relations with the government so as to maintain his privileges. Sometimes, extremely rich people are more prone to "forget" how the reality of common people actually is.
