you and Bachira met as children, you were older(abt 4 years or more if you want) than him so he wanted to be like you, hence his passion for football

he always played football with you and it gave him joy, but one day..you just disappeared, he couldn't find you anywhere, only after a few days he found out that you had moved

Bachira hasn't made any friends since then (even though he really wanted to) and he replaced playing ball with you with playing with his monster

after a few years, bachira almost forgot about you, after all, he hadn't seen you since he was a child, bachira was now 15, that day he decided to watch a football match between Japan and some other country, then he saw you, the newest, top player of Japan, he recognized you immediately, and he remembered everything
