sorry to disappoint actually... I do feel that her smile and politeness was an invitation
Her smile and politeness is the way she is. She talks sweetly, maybe because thats her nature or maybe because she is a foreigner and is trying to adjust in the house where everyone knows everyone via some source and she might feel left out. So her way of talking is nice and sweet to gel around with people.
Had it been gauhar and arman would have talled to her like that and she would have sweetly politely asked him to stop and then later would have started crying, i would not buy it. Because she is fiesty one and thats her nature.
Eli's nature is more sweet and docile type plus she is foreigner and arman is big rude chauvinist guy. So i don't think her asking him to stop politely was any invitation.
