It's the last day of school, and the girls are excited because they're going to a party at their friend's house. One of the girls is going to make a cake, and she's going to have to bake it herself. The girls decide that they'll buy a cake from the family that's bringing it to the party, so they can make their own cake if they don't make it. The girl who's making the cake, however, doesn't seem to mind at all. She just wants to show the girls how to bake a cake. First, the girls put apples in a pot, lemon, water, and granulated sugar. Then they make a mold of the supposed apple jam, cut parchment paper, and use pre-cut paper to make the chocolate mold. Then the girls crack the eggs and put them in a bowl. They're ready to bake the cake when they hear the girls talking about how nice yuka is. The cake is done, but yuku and her mom are about to use a hand mixer to make more dough, so the girl who made the cake is crying.
