banishing would mean dishonour for Mayuri, not the house. And she want to avoid dishonour for the house she feels obliged for her life. So I guess that calls for the way to get her out without the house being put in bad light (hope this simile exists in english) That means...we find a way that allows Myuri and the house to depart ways, while the house cannot be accused of failure or lack of responsibility etc. This means violent solution is out of question...even threatening their guests would call for retaliatory strike from them so they dont loose the face...
Huh this is quite a hell...it seems that this culture is firmly bound by responsibilities, code of honour and obligations...on the other side, man, who accepts this...and finds his way around...is almost completely free to do anything he wants to. We would hardly come with proper solution without Mayuris help. On the other side...our power lies in Out-Of-Box thinking and action...hope we can use it as advantage...
