This is a problem that almost everyone will encounter. First of all, as a freshman, you should relax and not be so nervous. We are all of the same age and get along well. And there are four people, not many people. Since you want to be a roommate for four years, you must get along well, or you will be worried.
First of all, learn to play together and have fun together. Never break up with someone in the dormitory because of personal emotions. Second, if there are inevitable contradictions, you should treat them with your heart, speak with your heart, and don't do things with your conscience. When you go to college, you will know that you can only rely on your roommate.
Third, don't be infatuated with your roommate's boyfriend and don't be jealous. A woman's jealousy is the most terrible.
No one can fool a roommate. I think if you treat them as sincerely as your sisters, you will surely get their true friendship.
Finally, I wish you a happy four-year college life.
I hope my answer can help you. Thank you for your adoption. ?
