To infiltrate a dangerous criminal organization, the duo must rent an apartment inside the syndicate's hideout building and pose as a newlywed couple. The tension skyrockets when the criminals become highly suspicious of them because they fail to hear any "marital intimacy" through the thin apartment walls. To protect their identities, save their lives, and complete the mission, Riko and Noma are forced to fake physical intimacy—a dangerous game that quickly blurs the line between a professional assignment and genuine, passionate romance.
