(HP) The Promise

I woke up one day and discovered I'd become a baby. I had no control over eating, drinking, or going to the bathroom, And I also found out I was one of the three scrappy heroes who defeat the Demon King in some fairy-tale novel! I've decided: stay away from the protagonist, stay away from trouble! But somehow, I've ended up with a fateful connection to the Demon Lord. Good heavens, that's trouble too! P.S. Updates will be incredibly slow, slower than a tortoise or a snail, and there's a very high chance this story will be abandoned. So think carefully before you jump in!!!
