It was alluded that adhik and pakhi intended to get intimate. Even anupama saw that and was about to break their moment if vanraj didn't come in time. They are right here.
The execution however highlighted the hypocrisy of Indian parents. No one questioned Toshu about his relationship with Kinjal?
The only reason Vanraj and Anu might be considered correct in stopping Pakhi to meet adhik further, is because audience knows Adhik has ulterior motives to get close to Pakhi. Their explanation of attraction, friendship and getting to know eo is valid.
