I really liked this, but instead of using ' for speech, you're supposed to use " for speech. It was kind of confusing to read at first because of that. ' is supposed to be used for thoughts.
Otherwise, really nice fic!

Noooo, my poor baby!

Loved this! :3

This was a good homage to Tony and how his death more or less affected Peters life, I wouldn't mind if you continued to write some more chapters with how Peter treats Tony's death as well interact with the rest of the Avengers.

So much uncertainty for Peter, but at least May and Happy are there for him. Well done, you capture the characters perfectly

Breaking my heart even more :(
