Matt came in for a bagel. He found so much more.
(or the fic where Foggy and Karen run a bagel shop and Matt is 'selfish' in wanting them both)

What if ten-year-old Matt Murdock never met Stick? What if Natasha Romanov, rouge agent, former assassin, and deadliest woman on the planet met a runaway child one day and, despite her reservations, found herself befriending him? What if the Black Widow adopted a little blind boy with preternatural abilities because she knew she could help him when no one else could?

Featuring running, fighting, cooking, dancing, intrusive archers, some inadvisable parkour, and an overabundance of paper cranes; building a family is never easy.

Matt and Foggy meet freshman year at Columbia, but they're entirely mismatched as roommates. This is the story of how they go from misunderstandings to pining to something else.
