So, let's get down to the story. You were riding to the academy in a carriage, your personal maid sitting next to you. You were already dressed in your school uniform. You approached the gate. You got out of the carriage, and the maid carried your things. You reached the dormitory, and the maid placed your things next to the bed. After some time , you finally unpacked your things. You sat on the table by the window and looked out onto the street. You saw Alicia yapping towards the gate, trying to persuade Oswald to let her through because she was late. And Yumiela watched everything happening from behind a tree. You were sitting in your room drinking tea. So , choose:
