@ mudraswathi...
I felt Nidhi should have taken the lead...because she is comfortable with Rohan and finds nothing wrong...But Ashutosh never touched any girl...so he may not be knowing how she would take it...I am telling this from my personal experience..., Ashutosh being my age and introvert I thought...he did with eyes...but aajkal ke bachche maante nahi...
Also, he was totally naive with females..he offered his kerchief to her and asked it back..Nidhi was taken aback at this gesture of his.
Whatever else was lacking no one can say there was no Ashni chemistry...Although Ashu di not touch her even once yet he conveyed all his feelings thru his eyes and his voice...In fact at times I found that more sensual than any physical contact...But as u said aajkal logon ko zyada physical contact hi chahiye...Anyways all this is in the past..with MB gone from the show we will now not be having much nainon ki bhasha but more of haathon ki bhasha I guess...
