i think she would behave something embarrassing and foolish like trying to get close to him or kiss him or hug or something similar and Armaan would stop her and bring her back to her senses and then she would feel
embarassed and realise that he has not taken advantage of her and that would make her respect and love Armaan all over again, and this time with more intensity.
coz creatives still have the scope in storyline to extend it for another three four weeks by showing Riddhima following Armaan and then eventually Armaan giving in.
If this happens we would still see romantic scenes between AR like Ridz wooin Armaaan, following him, caring for him,bringing food for him,and giving him same cases as hers since she would be the monitor now.
My personal instinct no confession but only turn of tables but i guess that would be fun too coz we all know Armaan is gonna give up soon ,he always makes promoses to leave Ridz but the very next day he is back to square one ,so no more hope in the dialouge
