That ‘guy friend’ is used to hearing her say all guys ain’t shyt. His confidence comes from always being seen as better-than. Most guy friends eat off womens’ naïveté. The guy can be seen as some grand oracle who can dissect what guys ‘really’ mean aka ‘he’s full of it’. He’s the only ‘real one’ she knows
So when another ngga comes in the picture who’s legit, the guy friend gon break down

He gon try to cash in that goodwill bc he don’t want her seeing better. I seen it comin a mile away and never even met him
