Big Problem With the X-Ray Stickers / The Human Book Cover

When Nobita uses an X-Ray Sticker on Dekisugi's notebooks to copy his homework, he accidentally views an exchange diary between him and Shizuka where they both criticize Nobita's dependency on Shizuka. Infuriated, Nobita writes some insulting things on the monitor which end up showing on the actual notebook, and now he has to find a way to erase the text before Shizuka and Dekisugi find out what he did. Dekisugi thinks of a clever idea: He collects everyone's classwork and tries to match the handwriting. Nobita shocked by the news, runs to Doraemon. Doraemon there had already cleaned the mess completely, which took the scribblings away from Shizuka and Dekisugi's book. The episode ends with a surprised Shizuka and Dekisugi.
