My sister's dream is to become a school teacher. And this time, she will be in charge of my class as a teacher trainee. I want my beloved sister to do her best and make her dream come true. However, my class is full of DQNs and the class is collapsing, so I'm honestly uneasy. All the cute girls in the class were deprived of their virginity by DQNs. I can't sleep at night when I think about what if DQNs mess with my sister.
