a sign to reread: can't recognize the friend

lol don’t worry, if I remember correctly this was his first interaction on screen side by side with MC. The friend was shown in the beginning as a baby (the eating video arc) and was only mentioned in passing when MC moved to America after the timeskip. (The dad of the friend mentions him but the kid wasn’t shown)
To those novel readers (if there's a novel of this), did he show the other world to his sister or any other people? Or maybe bring someone from the other world to his world?
