Same here. I admired his drive and reasons for becoming the number 1 hero but his constant crying annoyed me. I only started liking him during the 1v1 tournament, and I loved his character during his fight against Shouto when he became full MADMAN. MADMAN Deku is my favorite stage of his character like his fight with muscle man Randy Savage.
Recently though it seems like his character has mellowed out a bit, almost as if his character is evolving, which is nice to see. It's not something commonly seen in shounen manga. I do hope we get to see more of MADMAN Deku soon because I really miss that part of his character.
