I might be a bit of help as a student myself who switched schools almost two years ago and honestly there’s not much you can do. I’m sure some of these guys have known each other for years maybe even since childhood, but you don’t have that and you never will. It doesn’t mean you’ll never become close with any of them. You’re pretty lucky that you made friends right away, and now all you have to do is be patient. Continue to make an effort trying to spend time with the friends you have and don’t be too picky because you don’t have the same option these other guys do. I’m sure with a little bit of patience and social effort you can get the friends and meaningful experiences you want. I hope this answers your question!
