It took a while for Dominic to regain his mental health. Although it can't be complete, at least his condition is much better than Jessica's, which continues to deteriorate. Not only because of the depression she experienced, but also because there was no desire to recover, which made Jessica's condition worse. In fact, Hans Yori and his wife were resigned to what had happened to their daughter.
They thought it was karma for all the bad things their daughter had done in the past. One thing that comforts them is the return of the nanny and the little girl who is Jessica's child, as well as the first granddaughter of the Yori family, who comforted themselves in a moment of grief by remembering their two daughters.
