Mura 正在与一位同事竞争晋升，而她并不喜欢这位同事，她一直试图想出一个可靠的方法，确保另一位同事错过她的面试，这样 Mura 就可以自动获得晋升。她最终想到了一个主意，那就是使用咒语来束缚她的竞争对手，确保她无法进入办公室。她从网上订购了一本咒语书，冒着可能只是骗局的风险。当这本书送到时，Mura 急切地想试试它是否真的有效。当她念出一个“束缚咒语”来测试自己时，它超出了她最疯狂的预期。但她犯了一个错误。现在她自己被绑住了，她拿不到那本书，也记不清那个反咒语了。她尽了最大的努力去重现它，但每次尝试她都会出错，这让她的情况越来越糟。当她不小心给自己设下了一个堵嘴的咒语时，她甚至无法说话，无法再次尝试解除束缚的咒语。Mura is in competition with a work colleague for a promotion, a colleague she does not like, and she has tried to come up with a reliable way to make sure the other girl misses her interview so that Mura will get the promotion by default. She finally hits upon the idea of using a spell to tie up her competition and make sure she can't get to the office. She orders a book of spells off the Internet, taking a chance that it may be just a scam. When the book arrives, Mura is anxious to try it out to see if it really works. When she enunciates a "Spell of Bindings" to test it on herself, it exceeds her wildest expectations. But she has made a miscalculation. Now that she herself is tied up, she can't reach the book, and can't quite remember the counterspell. She does her best to reproduce it, but each time she tries she gets something wrong, making her situation progressively worse. When she accidentally conjures up a gag for herself, she can't even speak to try the unbinding spell again.
