I agree with you on this completely TM. Zoya has friend zoned Aditya , even if she is attracted to him internally she has never fully admitted it to herself therefore this thought of him being in love won't even cross her mind.
I guess the issue is more that people want Zoya to feel that attraction visibly and vocally like Adi does. When they have these romantic trip and fall accidents, we need to see more of Zoya's mixed or confused emotions during this. Personally I would never admit I am attracted to someone unless I am certain there is a heavy indication from them that they feel the same way so I cannot relate to Adi confessing that he is in love with Zoya. Its so personal. Some people can outright say they love/like someone without caring one thought but most people would want some kind of hints to go on.
I don't like third angle wheel for this reason that it serves no purpose IMO. If Adi did not realize he loves Zoya then yes this could have been a useful track in his realization because who hasn't been jealous of someone flirting with the one they like. Now it is just a bit painful to watch him be so unsure of himself or have his heart broken. I guess the CVs want to show that Adi never fought for Pooja and he will for Zoya. Lastly I love angsty romances, so yeah while Zoya needs friendship her constant friend zoning puts me off a bit.
Everyone will have polarizing reactions to this track that is for sure.
