The very first thing someone did after returning to Senior Yang's mansion was Ronron telling him about what she did as a disciple in the sect for a month.
She laid out her entire month-long story for her master to hear. Senior Yang seemed slightly worried that she was left alone, but mostly he was happy to see her happy.
Alex introduced his mother to the senior, who gave him an earful of scolding for separating her from her family in the first place.
Alex was definitely surprised to see his mother ignore their age difference and scold the man.
Senior Yang took the words without getting angry or feeling insulted. He knew what he had done wrong from the start, but that was the only way he could have done things from the start. If given the chance, he would do it all over again.
