When Sensei assigns the students to do a sketch for homework, Nobita decides to ask Doraemon for a gadget to help him as he's terrible at drawing. Doraemon however refuses to do so, leaving Nobita to wander around the neighborhood trying to find something to sketch until he decides that he'll do a sketch of Shizuka. While arriving at Shizuka's house Nobita, finds out that Dekisugi is planning to sketch Shizuka as well and Shizuka invites both of them. While Dekisugi manages to do a well drawn sketch of Shizuka, Nobita's sketch ends up rather poorly and he decides to go back home, not showing Shizuka and Dekisugi what he has drawn. Back home, Doraemon uses the Anytime Anywhere Sketch Kit gadget to solve a memory issue that Nobisuke and Nobio were having. While Doraemon accompanies them, Nobita sneaks into the his room and uses the gadget to draw multiple sketches including a sketch of when the group was during the stone age, a sketch of Shizuka washing herself in the soap during a bath and finally a sketch of Shizuka smiling. Content with the latter sketch, Nobita goes back to Shizuka's house where he shows it to Shizuka and Dekisugi, impressing them. However, Shizuka and Dekisugi notice a few more sketches and decide to look at them, much to Nobita's horror. Meanwhile at home, Doraemon finds out that Nobita used his gadget and does a sketch to find him only to be confused and terrified as the sketch shows Shizuka angrily chasing after Nobita. Back in Shizuka's house, Shizuka confronts Nobita about the bath picture to which Nobita attempts to explain but is cornered. The episode ends Shizuka stating that she will never be Nobita's model ever again while Nobita cries out to Doraemon for help.
In the manga and 1979 anime the sketches contains a picture of Shizuka washing herself with a soap. This is changed to a picture of Shizuka soaking in the bath in the 2005 anime due to tighter censorship.
The scenes where Nobita sketches Shizuka washing herself with a soap and Shizuka showing Nobita that sketch were edited out when the 1979 anime version aired in India
