Arylie just married and started their martial relationship. Arylie had feelings before marriage too but they didn't mentally prepared for this relationship even though they're married. They had many questions, insecurities, disappointment towards EO, infact they're fighting their own battles but slowly and steadily events happened cleared the air on mind.
CVS beautifully showing the parallels, than Aryan imlie getting more clear he is the one for her, that's why her confession is more sensual and passionate than Aryan. Adi left imlie by seeing Arylie together and Malini manipulation now same scenario is happening. how Aryan is different from Adi that's the main plot âïž CVS trying to show on this track and they're beautifully building Arylie martial relationship with (love, passion, desire, pain)
Arylie already played fake marriage and fooled entire family till they got married for real, even now no one Knows that so I am not surprised they're playing this fake pregnancy. They're very much on lovers phase, enjoying EO company emotionally and physically. Like Aryan said they may have problems but separation and divorce isn't their cup of tea.
