Hope you can help me with this. I'm looking for an AU klaine fic where Kurt moves to his grandparents to Paris after both his parents die. There he meets Blaine, Finn and Puck. They are some kind of supernatural creatures who cannot die. They live together with some other people from ND and I think Will watches over them (or something like that). In the beginning Kurt sees as Finn or Puck dies in the metro saving some girl from under the train and a few days later sees him again alive as if nothing happened.
Hope this will help you recognise it. Thanks :)
