A sentence that shows the characteristics of a character by means of foil

I write about the kindness and tolerance of the Chinese teacher. I use the most dull and timid deskmate in my class to take the initiative to speak in her class. It can also be set off by students talking and laughing around the teacher after class.

Chinese teachers are the gentlest and most loving. The classmates are the most open in front of her. Don't believe me, you see, the deskmate who often looks down and blushes as soon as she speaks actually stood up on her own initiative in the earnest gaze of the teacher. Although she is still a little stiff, her voice is confident enough. As soon as the bell rang, the students were surrounded by teachers, talking and laughing. One talked about the interesting things in the class and the other talked about the new little sister at home. Everyone opened their hearts and poured out all the bitterness, anecdotes and even little secrets buried in their hearts.
