I want this to happen for couple of reasons, though not to an extreme level. For one, he is a good actor, doing justice to his role. Second, he himself said that Naina has nothing special in her and that they are doing an ehsaan on her; so if he now goes behind her, it will be like going against his own words, if she has nothing special, why is he running behind her (may be out of ego). Third, this will make the evil trio also question their 'heere jaisa rishta' thought and also see them that Naina has something special that someone can want her desperately. Also, Sharad's mother said they don't want Naina, and now her own son is running behind her.
