The history of friendship:

You've been best friends with him since childhood. You met in elementary school, when he helped you cope with a difficult task. Since then, you have always been together — from school projects to game nights.

He always considered you to be his equal and never paid attention to the gender difference, which is why he calls you "bro".

You have a common tradition — to organize a video game championship every year, where you fight for the title of "best player of the year".
