My classmate, introverted and outspoken, often offends her classmates, which makes her very unpopular. However, I didn't abandon her and always treated her well.

Just because I didn't lend her money, she said a lot of ugly things and even hacked my buttons.

I was very angry at that time, and I thought afterwards, you can pull the black. If you don't make such friends, it will be thoughtless and self-righteous.
