Was there love or not?

Zhang Bo raised his eyes as he came to a sudden realization. "I will have to move out as well, my son will not be living under the same roof as a murderer. I have acted enough of these dramas to know how the story goes. The illegal heir will scheme and try to take everything, killing all those in his way." 

Caishen was no fool and most of the things his brother was asking, he had asked himself as well. But what he didn't understand was Zhang Bo's lack of interest or joy at the possibility of the return of their father alive. 

He couldn't help wondering if he was being naïve for thinking that despite all the complications, the possibility of their father being alive was good? 

Caishen was certain that he loved his father. That was an irrevocable fact, and he had always assumed that Zhang Bo shared that same feeling. His actions now left Caishen with many doubts.
