Why Virat did not clear his stance with Pakhi for months - when Pakhi hinted at their relationship during basant panchami & valentine's day? He should not have beaten around the bush. Even before these, Pakhi went to her parent's home - after Sai's meeting with DIG. She would have found some stability. But Virat got her back to Chavan's house - even though Samrat was missing - which is another curiosity. He probably missed her - but it sent wrong signal to Pakhi. He delayed coming clean, also continued calling her friend, even now. That is not at all acceptable.
Pakhi has her own delusion - after a point, she refused to believe her eyes, ears or brain.
