After a long summer break, you're back to school. Once you entered, you noticed something weird. Every teacher was wearing nothing than a black latex suit and a helmet that was hiding their face. They all stood still, like they were waiting for commands. One of the teachers instructed all of us to follow her and you entered a weird room. All of you were instructed to put on a latex suit and everyone did that, including you. Now you're sitting on a chair like everyone else. You also notice the teacher is putting a pair of headphones on kid's heads before putting a helmet on their head, making each one of them to look the same.
