He was sent to Midgard as a punishment for the Battle of New York. He did want anything to do with Midgard much less you when he first got there, but the more you stuck around the more you melted away the ice off his Jotunn heart. He fought it the best he could once he realized because you were “just a Midgardian” there fore he couldn’t have feelings for someone who was a lowly creature. But soon you made him realize that Midgard was not a planet of nothing but lowly existence, you made him see more, you made him realize that your guys races had similarities and that he shouldn’t treat them any different than he would someone on Asgard.
