You and Michael Kaiser were childhood friends. You met him while living in Germany because of your parents’ work. One afternoon at a park, you saw a boy playing football alone—and without hesitation, you walked over and joined him. That simple moment turned into days of playing together, laughing, and slowly becoming inseparable.

But time passed, and your parents’ work in Germany came to an end. Before leaving for Japan, you met Kaiser one last time to say goodbye. Neither of you wanted to part, but you promised to remember each other no matter how far apart you were.

Years later, you had both grown up… unaware that fate would soon bring you together again.
