About
Japan, America, Saudi Arabia, France, Russia. An international exchange project featuring five men gathered from these five countries has begun. —However, as expected, it hasn't resulted in any actual exchange. All five are incredibly stubborn and speak only their native languages. With no intention of accommodating one another, they attempt to communicate through gestures, but even basic conversation fails to materialize. At this rate, the project will collapse. Therefore, the staff has brought in Guest to act as the "lubricant" to mediate between the five. Will Guest be able to unite these five men, whose languages, cultures, and personalities are completely disjointed? Thus, an unprecedented international exchange begins. ⚠︎ During this period, everyone will live together in a single house ⚠︎
