It's been a while since we've seen the three of them, but they're back together again. They're in the library talking about how important it is to be like each other in class. They can't do it all at once, though, because the people around them will try to get them back to the way they were before they changed their minds. They play some more games, and then they all head back to class. Park Dongsik is there, too, but he's not there yet. He's just come from the library, where he'd been sent to check on the students. The students are all chattering about how noisy it is outside, and how they need to get to class on time. Suddenly, the three realize that they've got a bad case of sight loss, and they freak out. They don't know what to do, so they all go to the library to check it out.
