Naughty Little Green Plum

On the first day of transferring school, Su Niannian discovered that her new deskmate was her little brother whom she had lost contact with for ten years. It's just that this little brother... Doesn't seem to want to pay attention to her. She fell asleep in class and disappeared after class. The first thing she said to her was—— "Su Niannian, do you still dare to appear in front of me?" Su Niannian felt extremely wronged. She didn't want to move, why did she make it seem like it was her fault? . Until she found a note in the textbook with five words written on it: "Stop disappearing." Later she found out that he had been waiting for her for ten years. Every year she goes to their secret base when they were children and guards the iron box she hid.
