How can you befriend the Good Masters?

[EricGN]

I fucked up, I accidentally click the wrong choice of words for communicating the Good Masters of Qohor. Now I can't ask him to give me one of his Unsullied. Also when I saw him in the open field of Essos, he gave me no chance of communicating with him except attacking me with his 400+ Unsullied troops. How can I befriend this guy? I really want Unsullied in my party.

Sounds like you really pissed him off.

Unfortunately there's nothing you can do at this point other than start a new game or reload earlier save (if you have any)

Well...shit, can't help it then.
Thanks anyway.
