If you still accept the friendship that has gone sour, then I can tell you that nothing is irreversible. If you deceive them, then the grudge in others' hearts is like crumpled paper. Even if it is smoothed out, there will still be traces; if it is others who deceive you, then the problem depends on how tolerant you are, but it will often not return to the original state. The other party's unwillingness to repair is actually just an attitude, not absolute. He is remembering the past in this way. If someone doesn't value this friendship, they won't even remember it, let alone these things! Don't hit the smiling person with your hand, just be sincere and you can do it!
