The Fl is lost love kind off ML old brother they were in same school I guess and he used to like her ...... I just saw the raw with that I somewhat kind of thought and the lady who was with the ML old brother is doing all the evil things to Fl and acting innocent in front of everyone. Then after all the things get to know ML and his old brother they throw her out of the work . But the great granny get fooled and bring her home and FL life become more hell and btw she ends up with FL ex-husband.... That I guess (PS I don't remember there name )
