It was not directly stated in The Melancholy of Haruhi Suzumiya that Haruhi has feelings for Kyon but it can be assumed that she had because of her attitude towards him (like trying to fix her hair in pony-tail since Kyon told her before that it suits her, or having Kyon the only person with her when she subconsciously wanted to change the world).
And it wasn't also directly stated that Kyon had feelings for Haruhi. More frequently, Kyon is shown to have feelings for Asahina instead. Though, there are times that it can be seen that Kyon cared for Haruhi.
My question is, was Kyon in love with (or did he developed some affectionate feelings for) Haruhi? If so, is it possible that that feeling was caused by Haruhi's power and not Kyon's real feelings (since Haruhi can just think of having an esper, time traveler and alien would be great, and it will exist)? If he is not really in love with Haruhi or if he is in love with Asahina, then, why isn't he affected of Haruhi's power (assuming that Haruhi thought that having Kyon in love with her would be great)? Or is it that Haruhi didn't think of something like that (this seems to be impossible since she even dragged Kyon when she was about to change the world) or she's not really in love with Kyon (seems not the case as well)? Or Haruhi's power doesn't affect people's feelings? If Kyon is really in love with her (from the bottom of his heart and not from Haruhi's powers), then how can it be? Was Kyon the exception to Haruhi's rule or Kyon can somehow nullify Haruhi's power?
