I think it was gradual progress as love should be. It started with them taking solace in each other's presence. To find a motive to be alive for something even in those times of grave misery. They fought just to feel anything except brokeness and deep failures of their marriage. Then they got gravitated towards each other due to the kindness and purity and hidden strength they saw in each other. Aditya was always very opena nd vocal about everything so it felt he gravitated towards her first but the same time Zoya also started seeing him more of a human rather than husband of her ex husband's gf. That first riot near the office got them thinking about each other and suicide track solidified it for Aditya whereas Virani shaadi function solidified it for Zoya. From there they had strong connection as hamdard and friends and Jungle track brought them more closer to each other. Those six months really showed them the importance of each other in their life. As for realization Aditya got to that padav first as he always craved for Bepannaah love and he had mentioned it on several occasions in the past too whereas Zoya completely closed herself for future love scenario. This journey was so beautiful and every turn made them love eachother.
THEY THEMSELVES DON'T KNOW WHEN THEY FALL IN LOVE EXACTLY.. WE AS SPECTATORS IN THEIR LOVE LIFE CAN'T PINPOINT IT AT ALL. THAT'S HOW LOVE SHOULD BE.. SLOW AND GRADUAL.😳❤️
