In one part, Kurt promises Blaine he'll take him to his house the next day for a tea party, but Kurt doesn't show up at the park. Blaine waits for Kurt all day at the park. The next day Kurt say's he's sorry for not coming, but it was too hot and his parents wouldn't let him.
Blaine and Kurt remained friends and the story shows their friendship through the years. I remember Blaine is put in a foster home and him and Kurt lose touch for a period of time.
