What if... when Natsu first got to the Fairy Tail guild he never trusted anyone except Master Makarov and Guildarts. What'll happen when Lucy comes into the picture? He doesn't trust anyone and lives his life wondering where Igneel is. He's considered mean and evil. Nobody knows squat about him but he knows everything about everyone except the new girl.

(A Fairy Tail Fan Fiction) What if it was Lucy who Natsu knew as a kid instead of Lisanna? 10-year-old Lucy Heartfilia decides to try something risky... she runs away. Having absolutely no clue as to where to go, she is completely lost, until she meets a misunderstood stranger who seems to understand her struggles.
