Kurt was surprised when he saw Blaine and the Warblers come into his school but he knew that they wanted to say goodbye to him. When Blaine had opened that beautiful mouth of his and started singing, Kurt felt a rush of love run through his veins. Blaine was so beautiful, standing right in front of him, serenading him. Kurt wondered if Blaine would ever know how much he meant to Kurt. Blaine had helped him through so much. Blaine had helped him through the Kurofsky incident, Blaine helped him to adjust with being at a private school. Hell, Blaine had opened himself up to Kurt after a few moments of meeting him. Kurt felt special. And watching his boyfriend sing to him, Kurt knew that he was luckiest guy in the world.
