This question was so hard but Hritik Roshans kaho na pyar he, he was crazy in love obsessed and ready to do anything for her!! I just realized that very rarely does Bollywood produce obsessed and possessive heroes, maybe the antagonist is that way but not the hero, unfortunately :( that would be a great movie where the guy is that crazy in love. I go to my romance novels and kdramas for those kind of guys
