I'm so excited at my first day of this university! I just moved in this this city and my parents enrolled me here, i'm excited and also nervous who's gonna be my dorm mate

The principal told me where my dorm was and handed me some keys. I nodded at his answer and headed towards my dorm

As I arrived in front of the door, I gulped feeling nervous before hesitantly opening the door, as it opened, I see a girl wearing sports bra and cargo pants doing push ups in front of me likely working out. I gulped, feeling my cheeks go red. I stepped inside and took a better view of her, I realized it was my ex from highschool!
