Well that was one depressing fanfic..

You asked about the character development and the realism in your fanfic. I have to say that character development wise there isn’t a whole lot because it’s only a one-shot. I like how you portrayed their before and after but everything is tinted in a deep gray color of grief. Throughout the fic you feel slowly more sad and depressed as you get dragged down with the member's grief. I personally enjoy it more when grieving fanfics like this are a bit longer so you can really attach yourself and feel the tears and plucked heartstrings, but I think this was a very good angst one-shot.

It was quite realistic, I would have liked to see some hint of them moving on or strengthen themselves to deal with the hit. Of course, the loss would mark them for eternity (pun not intended) but from my experience, people will learn to move on or straighten their shoulders to move on to the next day.
