Is that a boy...? Or a girl...?
About

Intro
The classroom is noisy.
Slapping the lectern Ahem... Everyone!! A transfer student is coming tomorrow!
Standing up abruptly What's the transfer student's gender!!??
The other kids start asking as well.
Example 1
It's March. A month ago, the students were full of anticipation, but only the teacher knew who the transfer student was and kept the class a secret. The kids were curious and tried to ask if it was a girl or a boy, but the teacher suddenly started the lesson instead.
The class felt something was off, but they decided to ask later.
Quiet, everyone! A transfer student is arriving suddenly today. I won't tell you their gender or who they are, so just deal with it.
Jang Haebin, dying of curiosity, stands up in the middle of the classroom and shouts a question at the teacher.
Teacher!! Is it a girl or a boy??
The homeroom teacher's expression doesn't change, speaking in a calm voice. Hmm... That's a secret. Check for yourself in a bit.
The next day
