As he said, the father pretended to be sick, because his mother had died early and no one could take care of him, and his work was piling up, so Aman decided to tell his wife to come take care of him, all in the plan of the lustful old man.
Knowing that Aman would not let his wife stay here for long, the father decided to find a way to come live with his son for a while so that his daughter-in-law could "take care of" him, because he loved his father, the filial son could not refuse.
Although the daughter-in-law knew she was being taken advantage of, she still chose to remain silent, partly because she wanted the father and daughter to not have any conflicts, and mainly because this girl was just as lustful as her father-in-law.
