We went to different universities. We had a video call. She kept on looking to her left while on camera with me, and I assumed it might be her flatmate. Thereby She then tells me that she has a project to complete. I tell her goodbye, but instead of signing out from Duo, I just turned off my camera. She then sighed and gestured to someone else not in the camera to come to her. A boy comes into the camera, and they were flirting, chatting, eventually kissing while I watched in shock.
