I think Iris and Zihao have the same problem with not fully accepting their new identities. Iris doesn't want to think about who she was in the past and Zihao can't accept that he's not fully Nikolai anymore. But Zihao might be worse because he can't accept any of the love he's received from others.
hhmmm....first of all, the vetrov siblings should be thankful for their 2nd chance at life, 2nd, they should be grateful for Xiulan and zihao being their vessel bodies...they are the occupants, and having xiulan and zihao's identities, they also inherited both their families resources, which really gave them ample opportunity to accomplish easily their personal vendetta...having said that, I personally.wish that they should really accept that fact and live on the present identity and not linger with the past.
