  Summary

  "I could wait for you forever."
  "What if forever isn't long enough?"
  "Then I'll wait some more. I'll wait and wait and wait. There is no lifetime when I don't want to be with you."

  Regulus Black was just trying to get through Hogwarts without any problems (except the upcoming war and the fact that his mother has just signed him up to be the newest death eater). But of course with Sirius and most importantly James Potter there things are bound to get worse, or maybe better? Love Or Hate? Together or Apart? Friends or Enemies? Do or die? What will happen when their worlds collide?

  Or

  au of the marauders at Hogwarts in 1976 when they're all in school at Hogwarts. This is starting with Regulus in 5th year. What would have happened if the Black Brothers rekindled their bond and found love along the way?
