Firsts (слэш)

There is a series of firsts in his relationship with Barba that Sonny considers to be far more important than the usual firsts. They’re not the kind of firsts you’d normally remember, much less keep in your Memory Treasure Box to take out and marvel and smile at every once in a while, but most people would agree with Sonny on Barba not being exactly normal.
So obviously the important firsts with him wouldn’t be, either.
