The grudge between Zhang Xiong and Song Family Master shouldn't involve Zhang Yishan at all. They are your son-in-law; what's wrong with taking in one more person?
"Tang Rao, my mother and I owe you so much. Although Zhang Family treated you that way, you still repay grievances with virtue. I deeply apologize for what my father did to you."
Zhang Yishan never knows what to say to Tang Rao. When Tang Rao says he wants to treat Zhang Yishan and Zhou Juan as his own family, Zhang Yishan can't hold back anymore, apologizing and thanking Tang Reai profusely.
It made Tang Rao feel embarrassed to tell Zhang Yishan that he's actually plotting to take advantage of Zhang Family. He really shouldn't mind these true feelings.
"It's okay, whatever unpleasantness we had before, it's all over. Being happy in the future is all that matters. Yi Shan, we're brothers."
Ah, brother, does what you say make sense to your conscience?
