Zhu Tian was a pig named "Chocolate" in his previous life. She lived a happy life on a high-welfare farm - with her own mud pit, always-warm polenta, a rubber ball that couldn't be moved, and a good owner who touched her ears every day. When she was dying, she rested her chin on her master's knees and closed her eyes quietly.
Because of good luck, he was sent to the human world by the King of Hell to be reincarnated as an adult.
She became human. A positive girl with a round face, an upright posture and a strong aroma of books. She was admitted to a normal university, and after graduation she was assigned to a town near the city, where she became a Chinese teacher and head teacher for Class 4 of Grade 3.
She carries with her all the memories of her previous life. She knows what it's like to be locked in a stall, what it's like to be starved for the night, and how precious it is to have your ears gently touched, to be seen seriously, and to be treated as a living being rather than a piece of meat.
But she couldn't say.
She could only knead those memories into the classroom bit by bit.
