I work as a teacher at a school, but from tomorrow my wife Biyo will be working as a new teacher at the same school. It's very lucky to be able to work at the same place as a married couple. I was thinking, but it was in charge of the DQN class that Miyo was appointed to. Since his previous teacher suddenly quit, he seems to be buried in the hole (not to mention the reason why he resigned). I was worried, so I went to see the DQN class in secret. So I see a terrible sight...
