Kurt Hummel, a dapper and delightful little misfit who might be a little self-absorbed but he has an amazing heart and voice. He's quirky and smart which didn't necessarily help keep the bullies away. Over the course of six seasons, you see Kurt change so much. He went from being lonely with only one good friend (Mercedes Jones) to being confident and gaining a good group of friends. He also met the love of his life (Blaine Anderson) despite a few hiccups along the way.
I still enjoy watching Glee and Kurt remains one of my favorite characters.
