And at last
( I added the broken laptop that Black broke after he read the emails)
Ameer, as White warned Black, wasn't able to bear the kind of life Black lives without trying to help, so he turned to his family for help just like he did with everything else he faced.
Black trusted Ameer with his problems regardless of what White told him and he never knew that Ameer talked to his sister about his condition.
After Ameer died, and Black didn't have that much of contact with his family nor he had White with him, so when he felt lonely he just logged in to Ameer's e-mail and found all the emails between him and his sister talking about Black.
The lines above in the emails are parts of what he read.
What's the big deal with that?
Black consider that the grey he hates coz Ameer was one of the whitest people he even met. He couldn't really tell why a person as sweet and pure as Ameer would talk to him behind his back like that when he trusted him not to.
Whoever didn't get what Ameer did isn't reading it wrong nor is stupid. Also, I'm not writing wrong; I'm not a pro but I have two people that read chapters as I finish them and they got it without me explaining it and the people that recently stumbled upon the story and read it all by chapters got what's going on.
So, it just got lost or forgotten during the time in-between updates.
Sorry for any misunderstandings.
Have a lovely day <3
