Describe a person you disliked at first but ended up being friends with

One person I disliked at first but later became friends with was a classmate of mine named Minh. When we first met at university, I found him quite arrogant because he often interrupted people during group discussions and spoke as if he knew everything. To be honest, I tried to avoid working with him because I assumed he would be difficult to cooperate with. However, my opinion changed when we were put in the same team for a presentation. At first, I was not very happy about it, but I gradually realised that he was not trying to show off. He was just very confident and sometimes a bit too direct. In fact, he worked extremely hard, helped weaker members of the group, and stayed up late to edit our slides before the deadline. After that project, we started talking more outside class, and I discovered that he had a good sense of humour and was actually very considerate. I think the main reason we became friends was that I stopped judging him based on my first impression. This experience taught me that people can be quite different once you really get to know them.
