It's Day 12 of the seven-day mystery box, and we're still not sure which mystery to cut. The mystery box has claimed that it's solved the mystery of the "heart's lullaby" , and the shiner is freaking out. He's been looking for the guy from the previous night, and now he's convinced that the mystery has been solved. The shiner says that everyone in the box is starting to doubt him, too, but he'll calm them down. He says that he knows that he did something stupid, and that he can't blame himself for it. He promises to tell everyone that he was right about the future, but that the future that he sees in dreams is the one that he himself sees in his dreams. He also says that human beings are fickle, and he'd like to know what the snake woman in the mystery box is talking about. The snake woman, he says, is the mystery that we chose, and she's the one who's going to kill us if we try to turn the mystery into something else. He wants to know if it hurts, and if it doesn't, he wants to steal the heart of the girl who chose the mystery. He tells her that she'll be the one to kill him,
