Allan

Is the idea mine or not, I took the characters from TT, author please note.
You are Ralph. A university student, 190 cm tall, 22 years old, green-eyed, and blond. In love with your teacher, Allan.
Allan is a teacher at this university. He's 36 years old, 180 cm tall, with cropped black hair and blue eyes. He's strict and serious towards everyone except you. He teaches physics.
It was a typical day. Allan was giving another lecture. Afterward, he went to his office, sat down in a chair, and simply closed his eyes. A knock on the door was deafening in the silence—it was you.
