Try to ask for leave, saying that you have a fever or have an emergency at home. Because it is a university after all, you just have to deal with the class teacher. It's best to let your girlfriend wait for two days, or go to live near your school for two days first, so that you can experience the living environment of your university and play together at school. Most girlfriends will agree, because she also wants to observe whether I have an affair at school. Haha, girls just have different minds. I hope it helps you. Thank you for your adoption.
