I haven't seen the epi but couldn't resist to comment on your post.. :)
Both are aware of this attraction. But denial is from Anjali's side because she might not want those feelings to develop further coz she knows she has to marry Vidhaan as per her father's wishes.
When Sarita caught her talking on phone to Aakash, she had completely denied it but i felt that she accepted her attraction towards him whilst talking to Sarita on the phone that "iske baad shaadi karni padegi" and that look on her face while looking at Aakaash from the window which caused her to ignore Aakash.
I am excited to see what happens next and how but screw exams , have to miss epis...
P.S. your posts are always a treat! :)
