it’s not but this is just some suspect af shit if you ship them

• “Not only do I play a hero, but I play the hero’s hero. His hero.” -Harrison Ford on the relationship between Han and Luke. To which Mark replied, “He is, in effect, the hero’s hero.”
  
• That time Harrison kissed Mark instead of saying “That’s two you owe me, junior.” (I can’t find the picture of the interview where Mark said it but chances are if you ship them, you know about this. If anyone has it, please add it lmao)
• This entire picture.
• That one time Mark basically said Luke’s gay. He said something along the lines of “If the only woman you ever fall in love with is your sister, that should tell you something,” when asked about Luke’s future. (Again I can’t find the video and it’s late and I’m like 400% too lazy but if you have it on hand link it)
• Han and Luke were originally written as love interests and a lot of plot points involving their romance remained the same  and here’s a picture of it
• As far as actual moments in the movie go… There’s the fact that the only moments it’s implied Luke has a crush on Leia could also be seen as him having a crush on Han. “What do you think about her?” “I’m trying not to, kid.” “Good.” and “Do you think a princess and a guy like me-” “No.” Not only that, but especially for the 70s, it’s pretty weird that Luke didn’t have a canon love interest. If you watch him while looking at Han, he very clearly checks him out often (literally the entirety of their first meeting is Luke trying to smolder). Knowing that Mark thinks of him as gay, I wouldn’t doubt that’s how he played it even if it definitely wasn’t in the script (and knowing how George is, it wasn’t).
