Prepared by Movies Dock Editorial

Maybe We Could Have Killed Each Other Last Night follows a married couple whose hidden pasts and growing suspicions turn domestic misunderstandings into an increasingly dangerous situation. Blending comedy, romance and thriller elements, the Japanese film centers on identity, trust and the lengths two people may take to protect their relationship.

Maybe We Could Have Killed Each Other Last Night is a Japanese genre blend built around a marriage full of concealed identities and mistaken suspicions. Mitsuhiro and Sakuna meet on Halloween, marry, and begin what appears to be a happy life together—without either revealing the truth about their past or professional life.

When each starts to suspect the other of having an affair, their relationship takes a sharply unusual turn. The film combines romantic tension with comic absurdity and thriller stakes, creating a story where protecting a marriage may become more dangerous than the original misunderstanding.

Story without spoilers

The film follows Mitsuhiro and Sakuna, a couple who meet on Halloween before marrying. Their marriage appears peaceful, but both have kept important parts of their identities hidden: Mitsuhiro is a former yakuza, while Sakuna is a successful entrepreneur.

Their private secrets become even more complicated when misunderstandings lead them to believe that the other may be unfaithful. As suspicion grows, the couple tries to safeguard their relationship, setting off a series of dangerously absurd developments. The premise places domestic trust at the center of a story that moves between romance, comedy and thriller territory.

What to expect

The supplied genre information points to a film that mixes relationship comedy with romantic conflict and suspense. Its central setup is driven by hidden identities, marital suspicion and escalating misunderstandings rather than a straightforward love story.

Viewers can expect the tone to balance the intimacy of a troubled marriage with the heightened danger associated with a thriller. The contrast between Mitsuhiro’s former yakuza identity, Sakuna’s business success and their apparently blissful home life provides the foundation for the film’s unusual comic tension.
