Oh, I didn't mean that Alhaitham loved him more like that. It's just that Alhaitham is the one without hang ups and past grievances. He's more willing to love and be loved. Meanwhile, Kaveh has his insecurities in life plus it wasn't really clear if he has already gotten over what happened to him.

I think that Alhaitham won't shove his love on the other until Kaveh is finally willing to sort out his emotions and risk loving people deeply again.
