I saw his face again from a window crying after having an drama w a classmate

Ok so for context , I talked about my boy best friend (Ex) called A (or Alex) and like we were at biology class when I see him and another classmate and my French teacher talking to them then I see alex crying while my French teacher hugging both of them and making peace and I was like "awwww". I ALSO YELLED AT HIS FRIENDS AND HIM "67". Also my bff saw him on the same tram as her
