In Secret Mission 1, undercover agents Riko and Noma move into a building full of criminals while pretending to be a happy newlywed couple. There’s just one tiny problem: their nosy neighbors notice that the supposed lovebirds are awfully quiet at night. To keep their cover from falling apart, Noma suggests making their relationship look a little more convincing. Riko is great at her job, but pretending to be affectionate with her younger colleague? Yeah, that’s a whole different kind of assignment, and things get awkward fast.
