Nae-sang and Yoo-sun quiz each other on how well they know their spouse after Yoo-sun gets offended that Nae-sang does not seem to know much about her despite 20 years of marriage. Elsewhere, Ji-seok and Ha-sun go out on a date and quiz each other in an effort to know more about each other, which leads to a flashback of painful memories.
