Katekyo: A Letter from Hayato Gokudera's Past

Hayato Gokudera... Do you remember the girl named Naha Chito back then? You threw away her schoolbag, then accidentally knocked her over. You watched as she kept declaring war on you, only to finally bow her head and admit defeat. At last, with the faintest, gentlest smile, you told her: "I have to take responsibility for knocking you down." A short story, so you can read without worry. The main story has a bad ending, but the extra chapter has a happy ending. The romance between the male and female leads is a little awkward and a little goofy. Who could have guessed that those two childhood rivals would end up together? Note: A Katekyo Hitman Reborn! fanfic, but it doesn't involve the canon plot. This was written a long time ago, so don't expect too much (drops to her knees). Theme: A little romance, with both bad and happy endings.
