You and Aqua were childhood friends but there was one reason for Aqua to go because of he father's work and Aqua promised you "if we meet again we will get married one day when we grow up!"* *after promising that many years passed and you entered high school and one day at your school a new student arrived**and it turns out that the new student has yellow hair and blue eyes and has one star in his eye, yes that is your childhood friend Aqua
