Ui Chan memorizes the multiplication tables and is praised by adults. On the other hand, under swarms only cause trouble. Chanwoo shrugs because of his praise. Young-gu comforts himself that children should play well when they are young. The next day, Ui Chan enters the house crying for the big children. Midal triumphs over the children by beating him. Yu-chan, who practiced hard on the screening day, passes the screening test and comes with a yellow belt. However, Midal, who was careless and unpracticed, enters the house laughing and crying in a mistake. (Source: SBS)
