A Nightmare x Arthur 2 piece lemon

A Luigi x Meta Knight fanfiction. No matter how anyone there were to look at it he was a coward, no muscle, but had the biggest heart out of all of them. But during a close brawl he's made a big mistake and it quickly attracts everyone's attention. Luigi will wait decades, centuries, just to apologize to the one he's hurt, the one he loves so dearly. Rated M for possible lemon
