Chapter One: The Return

 　　"Miss, we've arrived, please get off!" the driver said, turning to the girl. But the girl didn't even look up, paid the fare, and got out of the car. The destination was the city's most famous school—Liying School. It has a history of over five hundred years. Although it's ancient, its facilities are unparalleled by other schools, and its teaching quality is top-notch, which is why everyone wants to attend.

　　The girl strolled to the school gate, looked at the large characters above the school sign, and couldn't help but smile. 'Sigh, finally, I'm back here,' she thought, shaking her head. She then lowered her hat and walked into the campus.
　　Entering the campus, looking at the scenery in the courtyard, the girl cried. She gracefully wiped away her tears and walked towards the principal's office.
　　'Knock, knock, knock.' 'Come in,' a deep voice came from inside. The girl gently pushed open the door and went in, but before she could even see what was in front of her, she was tightly embraced. The man said, "My dearest Xiaotong'er! You've finally decided to come back! I've missed you so much!"
　　Hehe! You probably wouldn't have guessed that the "Come in" he said was him, but it's true. And the "Xiaotong'er" he spoke of is our heroine—Bingtong. Bingtong smiled helplessly but didn't resist, letting him hold her. After a while, the principal finally had his fill of holding her and released Bingtong. Let
　　me introduce him! This principal's name is Li Hanlei, but those who know him call him "Uncle Lei." Only after releasing Bingtong did the principal begin to examine her closely. Bingtong was wearing a large hat that completely obscured her face, dressed in purple, and on her left wrist was a chain with a heart on it. This heart was pressed tightly against her left wrist, as if concealing something; Bingtong exuded an air of mystery.
　　"Little Tong, why are you wearing a hat? What happened to your appearance? Did something happen?" Seeing her attire, the principal couldn't help but ask. Bing Tong didn't answer his question, but instead took out a piece of paper and a pen from her pocket, wrote a few words on the paper, and handed it to the principal. Clearly, the principal didn't understand what she meant and blankly took the paper to read it. But after reading it, the principal froze, and the paper fluttered to the ground. (Uncle Lei, I'm sorry, forgive me for only being able to speak to you this way. My appearance is a secret, and no one can see it. Don't ask me why; I have my reasons. I hope you won't ask me why. I hope you can keep it a secret.) "Don't tell anyone I'm back. I don't want them to know where I am. If you want me to be alright, don't say anything, don't worry about anything, just consider it protecting me, okay?"
　　The principal raised his hand and affectionately patted Bing Tong's head, saying to her, "Poor child, although I don't know what happened to you, I will do anything for your safety. I promise you, your class is Senior Two A, so take good care of yourself. You can come to me if anything happens, understand?" Bing Tong nodded, then turned around, gently opened the door, and walked out of the principal's office. The principal watched Bing Tong's back thoughtfully, and then the door slowly closed.
