While playing Korean chess with Mr. Kim of the real estate, Soon-jae finds out that the deposit Joon-ha paid was not $10,000 as he said, but actually $30,000. Joon-ha insists that it was his friend Cheol-ho, who paid the remaining amount, and even says that he’d take a bow every three steps he makes if he’s telling a lie. Meanwhile, Seung-hyeon tries picking a fight with Yoon-ho, but steps on a shovel and hits himself, and gets into a series of following accidents. But Yoon-ho is mistaken for beating up Seung-hyeon and is called to the teachers’ office.
