So actually I got into a fight with one of the boy classmates today. Later on, I apologised him personally, and he said that it was okay, therefore he forgave me for what had happened. However, his friends are not happy about this, they said that no matter how much I apologise their friend, they wouldn't forgive me somehow, probably they are now holding a grudge against me I can say. I'm stuck right now, I'm not sure of what I can do to satisfy them.

Is it a problem if the boy I got into a fight with forgave me while his friends don't? Do you think that his friend can forget the incident later on as time flies? Please advise me, thank you so much. :)
