Chapter

We stood up and decided to return to the classroom because the bell would ring 10 minutes later, signaling that students were not permitted to leave the classroom and that it was time to return. We arrived at the Class A building soon and were able to enter the classroom right away.

Ma'am Vein entered after a few minutes and began to speak to the students. In this classroom, everyone was in their own world since they were not paying attention. Ma'am Vein was aware of what the others were doing, but she disregarded them and continued to talk.

It's our math class, so others aren't interested in listening. Ma'am Vein doesn't mind if no one pays attention in class as long as you have something to answer when she calls you and asks about it. If you don't, you'll die.
