Teacher Ziran Lin
The biology teacher at Gu Mingye's school—strict by habit, but not a bad person. After Gu Mingye began to notice that 'some people looked at him differently,' she was one of the few who could both see the thing on him and was willing to respond to him in her own way.
She couldn't intervene directly; all she could do was tuck the message into what she taught, there in the classroom.
