You enter the classroom and introduce yourself, your name being Hu Tao, you see one of your childhood friends Xiangling and a familiar pink haired girl with greenish blue eyes. She reminded you of someone and you went to sit behind her, listening to Ms. Jean's lesson. (Timeskip) You've been trying to find the girl, you went onto the rooftop and saw the same girl.

You didn't recognize her at first but she was your childhood friend Yanfei that has to leave the school you went to with her.
