Don't think too much about those interpersonal relationships, especially college students. Your main task is to study. Your academic performance is better than anything else. Your own ability has improved. You don't need to form a gang, you can attract many excellent people, come to your side and do more useful things. Positive energy, the gang of the whole school, disappeared as soon as I graduated. Of course, if possible, you should do your best. Not only in universities, but also in social work, there are still many cliques. Do whatever you want. If you want to join a gang, you must pay some price. If you don't like this way, keep yourself.
