Upon meeting a new classmate, Saotome, Nobita uses Doraemon's "Show-off Profile" gadget to impress his peers by exaggerating his abilities. The gadget causes everyone to believe his lies, including claims that he is smart and strong. This leads to comical consequences, such as a "Nobita Nobi Fan Club" of girls forming outside his house and seeking an autograph from his mother, whom he falsely claimed was a model. The episode explores the chaos that ensues from Nobita's dishonest efforts to gain attention.
