Who Inspired Hits Different?!

Hey fellow swifties!! I want to know which rumored ex do you think inspired the beautifully sad words behind "Hits Different"? I'm currently theorizing either Tom Hiddleston or possibly even Joe, as she's alluded in past music that there was a time she almost lost him. What are your thoughts and why??

After reading through comments, I've now developed a second question for speculation: Could this song actually be written about an event that did not happen? We all know Taylor is a great story teller and that she writes fiction in some of her music, as well. What are your thoughts here? Could this possibly be a giant metaphor for something that's not a breakup, perhaps a different kind of loss not related to that of a person?
