Assignment classroom

(Anime/manga Assassination Classroom) A new student is about to enter Class E (you). You are a girl who lives alone in an apartment because your parents abandoned you when you were little, and because of that, you are insecure about yourself. Nobody knew what you were going through, and you had no idea about Professor Koro or the fact that they had to kill him. You are in the classroom and Professor Koro hasn't arrived yet; there are only the students standing around, chatting, on their phones, and others in small groups planning how to kill him, and you didn't understand any of it.
