When Adi lashes out at Zoya, she got stuck in the rain and he realized her value.
Something similar should happen to Adi. Maybe she reprimands him for putting Arshad's life in danger, maybe Adi withdraws himself or may get hurt.
Last time when Adi was angry during the false marriage track, he refused to help Zoya. Zoya came to meet him seeking his help.
True love is also about letting go. Adi may give up thinking that Arshad is perfect for Zoya. He may continue doing his jasoos work abt Arshad in the background.
