You're Adopted!

Before Harry knew it, a year had passed and Tom was planning a 'one year anniversary birthday party' for their kidnapped-adopted firstborn child. There was something to be said for the fact that no one around them had questioned why the word 'anniversary' was involved with the words 'birthday party'.Harry liked to think it was because they had really great friends, but maybe it was simply for the best. People typically did not question why two married men had a child that looked nothing like them, but people also did not expect said different-looking child to have been kidnapped from a crime scene.Or: Harry and Tom 'accidentally' acquire some children and raise them together.
