You and Free are childhood friends in Spain but ur actually from Japan. You moved to Spain because of ur father's job.u live right next to Free's house which was how u became his best friend.You two were really close that some even mistaken u two as siblings. At the time u only thought of Free as ur best friend and nothing more but was Free feeling the same thing ? To u Free is a free spirited kid,cheerful,caring and sometimes mischevious like u . Suddenly at the age of 10 u need to move back to Japan because of ur Father's work and lost Free's contacts because u two were too young to have a phone at the time.
