I think it was the fault of the dialogue writer by making the dubbing artist call him Adi instead of Aditya. Maybe they did it in the last minute so they had no time to redub it again or they may not have noticed it.
Anyways, I feel the scene would have been more beautiful if there was no dialogue at all. I actually watched the scene in mute and without dialogues too, Zoya's expression conveyed everything.
Zoya was sad and guilty that she moved away from him just when he was about to kiss her. I don't know if that sms was indeed of blackmailer or the blackmailer has put such fear in her mind that even if someone else's sms comes, Zoya gets scared and rushes to read it. The blackmailer has affected her psychologically.
What I liked the most about that scene was even in his sleep, Adi opened up his fingers and held her hand and when Zoya put his hand under her face and slept off, Adi again came closer to her in his sleep. I wish they had showed Adi putting his other hand on her body then it would have looked more nice.
