The newly introduced nurse (Kim Mihwa) somehow has a bad relationship with Young Kyu. Yeong-gyu feels like he's met somewhere while looking at the US dollar and thinks about it. And Young-gyu, who had a fight with the US dollar and accidentally touched the bottom of the US dollar, is caught in the tail and falls into a situation where everyone should listen to what the US says. But soon, Young-Gyu finds out the identity of the US dollar and waits for the reversal of the bout. It looks elegant and so educated, but Suhyun accidentally asks for a crushing stone that Misun tries to throw away. (Source: SBS)
